Mark Shannon <m...@hotpy.org> added the comment:

Is this worthwhile?

Statically, BUILD_CONST_KEY_MAP represents 0.14% of all bytecode instructions 
in the standard library, but only 0.03% of the bytecode instructions in 
functions.
Which suggests that dynamically only 1 in 3000 instructions executed is 
BUILD_CONST_KEY_MAP. The implication is that making BUILD_CONST_KEY_MAP more 
complex is just as likely to slow things down as speed them up.

Do you have any evidence that this will make a measurable difference?
