Me too. I liked the leading _, but on second thought it is a weird language
change
re names in a special context. Probably not so good.
OTOH, I see in the above a generalizable principle of formal parameter
expressions as
automatic assignment targets at the beginning of function execution that could
allow
anything normally allowed locally on the left of an assignment. This is
contrived,
but illustrates:
def setem(key, adict[key]): pass # note that assignment is left-right,
# so key is available for adict[key]
# and adict is global here
adict = {}
setem('k', 'value')
adict -> {'k':'value'}
