- Two new functions:
-
- (character-index 'st_string 'xst_char)
-
- returns the position of the character xst_char in the string
- st_string. The position of the first character is '1'
- (1-based indexing was chosen because substring also uses
- 1-based indexing).
- If the character is not in the string, nil is returned.
-
- xst_char, as its prefix implies, can either be the fixnum
- value of a character (commonly written #/x), or a symbol
- or string, in which case the first character is used.
-
-
- (sleep 'x_seconds)
- sleep for x_seconds.
