Everything that comes after a hash character (#) or a double backslace (//) is ignored until the end of the line.
# this is a comment // This is also a comment print("Hello, world!") // A comment can start anywhere in the line
Multiline comments in boo are delimited by the /* and */ sequences. Just like in C. Unlike in C though, boo multiline comments are nestable.
/* this is a comment */ /* this comment spans mutiple line */ /* this is a /* nested comment */ comment */
Nested comments must be properly nested, however, or the parser will complain.
/* this is a /* syntax error */
