As in the R4RS, a semicolon (;) indicates the start of a comment.
In STK, comments can also be introduced by #!. This
extension is particularly useful for building STK scripts. On most
Unix implementations, if the first line of a script looks like this:
unspecified
error
makeotherˆ`=̀13`
gobblecr#!/usr/local/bin/stk -filethen the script can be started directly as if it were a binary. STK is loaded behind the scenes and reads and executes the script as a Scheme program. Of course this assumes that STK is located in /usr/local/bin.
