treated as signed or unsigned according to the column type.

* The stack contains one or more items, of which the first (bottom) one is
a string: Concatenates all of them together, which can be strings, numbers
(treated as unsigned), or classes. All formatting codes of strings will be
stripped, so that the result will be a unformatted string.


=== MML sound effects ===

The MML sound effects are similar to ZZT and MegaZeux. It is a string
consisting of the commands listed below (case-insensitive):

A B C D E F G
  Play a note of the current length and octave; notes outside of the range
  of a 88-key piano are not valid, but the quarter tones are possible. It
  can be followed by zero or more of the following signs:
  ! flat
  , half flat
  ' half sharp
  # sharp

X
  Play a silenced rest of the current note length.

W H Q I S T Z
  Set the note length to one of the predefined note lengths, where W means
  a whole note, the other letters are successively half until Z which means
  a sixty-fourth note, which is the shortest possible note.

.
  Multiply note length by 3/2.

0 1 2 3 4 5 6 7
  Set the octave to a specified number. Note that notes lower than A are
  not valid for octave zero.

-
  Low octave.

+
  High octave.

L
  Set note length to a following number of sixty-fourth notes.

N
  Play a note with the following note number, and the current length. The
  note number 0 is the lowest piano note, and then each next key on the
  piano is 2 more than the previous one (odd numbers are used for quarter
  tones that are not on a standard piano). Numbers 190 and higher are used
  for overtone notes; subtract 188 for the overtone number (although note
  that overtone numbers 0 and 1 are not usable).

(Note that this is not the same as standard MML.)
