: add-timestamp ( string timestamp -- )
timestamp>hms "[" prepend "] " append prepend ;
While compiling add-timestamp:
In word: log-message
Stack effects of the word add-timestamp do not match.
Inferred: (( object object -- object ))
Declared: (( string timestamp -- ))

yep, it should return a string at the end.
prepend takes two values, and returns one (the combined strings) so the word should have an output stack effect of one string.
