Interesting, I don't think assert.fs was included by default in v0.7.3 (at least that's what the error seems to point towards).

This should be easy to fix by just placing the closing bracket on the same line as the comment, which is definitely a no-op for Forth but should trick most syntax highlighting correctly :)

Will push a fix in a bit, thanks for reporting this @fgaz !
