to char[1], these checks should have been changed to Bucket.nKeyLength==0 * Support runtime declaration of functions. I ended up changing the grammar to catch top level functions vs. nested functions. The reason is simple - if we don't have functions properly declared at compile-time, function calls cannot be resolved at compile time, and have to be resolved at runtime, which ends up being much much slower (without the optimizer, that is). It's no biggy though, the grammar change isn't that bad.
