What about a 'special' keyword for special semantic scoping,
to control meanings within a block, e.g.,
x = 1/2 # makes zero because of special scope
special use_rationals, use_auto_bignums:
x = 1/2 # makes rational in pref to float
x <<= 65 # auto promotion to long of numerator
# back to (proposed) normal
x = 1/2 # makes float 0.5 as normal default
This is not exactly PEP-ready, but I thought I'd offer the idea.
Maybe 'special' might also have natural tie-ins to migration issues?
BTW, should I have posted this under a new heading?
