Thanks for the pointer! Both sides have good points.
I like locals declared where used whenever reasonably possible.
Even really good compilers can get tired trying to optimize 1000 line
functions.
Liveness tracking breaks down. Keeping variables local can make
everyone's job easier.
Agreed: verifying cleaned up code is exhausting.
thanks again!
