/*
 * Type values defined for Tcl_Token structures.  These values are
 * defined as mask bits so that it's easy to check for collections of
 * types.
 *
 * TCL_TOKEN_WORD -		The token describes one word of a command,
 *				from the first non-blank character of
 *				the word (which may be " or {) up to but
 *				not including the space, semicolon, or
 *				bracket that terminates the word. 
 *				NumComponents counts the total number of
 *				sub-tokens that make up the word.  This
 *				includes, for example, sub-tokens of
 *				TCL_TOKEN_VARIABLE tokens.
 * TCL_TOKEN_SIMPLE_WORD -	This token is just like TCL_TOKEN_WORD
 *				except that the word is guaranteed to
 *				consist of a single TCL_TOKEN_TEXT
 *				sub-token.
 * TCL_TOKEN_TEXT -		The token describes a range of literal
 *				text that is part of a word. 
 *				NumComponents is always 0.
 * TCL_TOKEN_BS -		The token describes a backslash sequence
 *				that must be collapsed.	 NumComponents
 *				is always 0.
 * TCL_TOKEN_COMMAND -		The token describes a command whose result
 *				must be substituted into the word.  The
 *				token includes the enclosing brackets. 
 *				NumComponents is always 0.
 * TCL_TOKEN_VARIABLE -		The token describes a variable
 *				substitution, including the dollar sign,
 *				variable name, and array index (if there
 *				is one) up through the right
 *				parentheses.  NumComponents tells how
 *				many additional tokens follow to
 *				represent the variable name.  The first
 *				token will be a TCL_TOKEN_TEXT token
 *				that describes the variable name.  If
 *				the variable is an array reference then
 *				there will be one or more additional
 *				tokens, of type TCL_TOKEN_TEXT,
 *				TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
 *				TCL_TOKEN_VARIABLE, that describe the
 *				array index; numComponents counts the
 *				total number of nested tokens that make
 *				up the variable reference, including
 *				sub-tokens of TCL_TOKEN_VARIABLE tokens.
 * TCL_TOKEN_SUB_EXPR -		The token describes one subexpression of a
 *				expression, from the first non-blank
 *				character of the subexpression up to but not
 *				including the space, brace, or bracket
 *				that terminates the subexpression. 
 *				NumComponents counts the total number of
 *				following subtokens that make up the
 *				subexpression; this includes all subtokens
 *				for any nested TCL_TOKEN_SUB_EXPR tokens.
 *				For example, a numeric value used as a
 *				primitive operand is described by a
 *				TCL_TOKEN_SUB_EXPR token followed by a
 *				TCL_TOKEN_TEXT token. A binary subexpression
 *				is described by a TCL_TOKEN_SUB_EXPR token
 *				followed by the	TCL_TOKEN_OPERATOR token
 *				for the operator, then TCL_TOKEN_SUB_EXPR
 *				tokens for the left then the right operands.
 * TCL_TOKEN_OPERATOR -		The token describes one expression operator.
 *				An operator might be the name of a math
 *				function such as "abs". A TCL_TOKEN_OPERATOR
 *				token is always preceeded by one
 *				TCL_TOKEN_SUB_EXPR token for the operator's
 *				subexpression, and is followed by zero or
 *				more TCL_TOKEN_SUB_EXPR tokens for the
 *				operator's operands. NumComponents is
 *				always 0.
