* 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
