The parser would have to know about comments.

If it's quoted, it may contain anything without interfering, no?

This is so at the moment, while all samples use AS .... LANGUAGE. This
could stay free format if quoted as usual, and require it strict if the
new format is used. Initially, I didn't want to suggest an additional
keyword like ENDFUNC or ENDAS, but now I do. If somebody insists on
using such a keyword in the function definition body, he could fall back
to the quoted format.
