Vista - Re: raising events by name

What is the point of reflection if you can't do what you need (raise the
event).

If you are making a game engine and want to expose some classes through
a scripting language and use reflection to make it work, this constraint
will cause hard pain as you will have to implement that dictionnary in
every class you want to expose to the scripting language, which could
easily reach hundreds of classes, not to mention this dictionnary thing
will become a performance issue.

Reflection doesn't solve world hunger, either...
Whereas with the approach of adding the Raise part to each event, you'd
have to have the same code repeated for every event. With the
dictionary idea you could even implement a common interface for all of
these classes, so it's clear what's supported.

As for your performance concerns, they seem *incredibly* premature to
me. Dictionary lookups are very cheap - and in the context of
interpreting a scripting language, they're almost guaranteed to pale
into insignificance. Oh, and dictionary lookups are usually cheaper
than using reflection, too
