that makes no sense. you only call the ones you know you need and store
the results in a hash. again, you are saying things which have
assumptions or knowledge about your needs which aren't clear. back up a
bit and show how you want to use this thing. show method calls and where
you want to interpolate them.

and slows you down even more as you have an extra sub call for each
method. also in that line you are destroying the method name with the
result of the call.

TT is not needed for this. not at all.
