I had inquired as to the possibility of adding strong typing during the last beta, but was quickly silenced by the backward-compatibility and internal architecture issues it would cause. Even if typing was optional, the internal logic branches in CF to handle typed vs non-typed variables would be horrendously complex.
I for one would love to see CF move into the strongly-typed world, but I'm not holding my breath. It's been making such incredible progress and is already so feature rich, that all of my wish-list items are pretty insignificant by comparison.

Then method overloading could be performed at compile time and restricted to only those methods with strongly typed arguments?
