This doesn't look like a dispatch table to me. If you're reading in a bunch of sub names from an external source, and calling them, order may matter. Hashes don't preserve that. "But I'm just suggesting using the table to convert from string to code ref! You can use the order of strings to control the order!" True, but why produce another hash when the symbol table (another hash) already exists, with ways to query it?

$ perl -le 'sub foo { }; print \&foo;print __PACKAGE__->can("foo")'
CODE(0xf81930)
CODE(0xf81930)

No non-strict code. And when I add new functions, no need to remember to update the symbol table - perl does that automatically.

Don't get me wrong. I like dispatch tables. I use them. A lot. This just doesn't seem like a use for them to me, mostly because it seems like the OP is trying to loop through them.
