I don't like directives that alter the semantics of
the thing being compiled. It's hidden global state
that makes it harder to understand the program. You
can't just look at part of the program to ascertain
that something somewhere else changed the rules.
I understand that this is the *lightweight* languages
discussion group, but I still think it's good to retain
solid, scalable "engineering" practices (for lack of
a better word) even in lightweight languages. I would
say that it's better to have a single semantics for
the language and throw out as many knobs as possible.
