This thread really isn't about variable naming. I'll simply say that I've always written the C idiom with `c` as the variable name, I've seen literally hundreds of others do the same, and I've never seen anyone spell it `input_command`.
I do the same in Python in a few contexts, usually where the variable's
meaning is very clear from its usage, or where the code in question
doesn't know or care what the variable is used for:
for i in range(10):
def get_const(self, x):
for k in self.defaults.keys():
etc., and if we had `given` clauses, I'd probably do this there too. I
think one of the advantages of that syntax is that it makes it extremely
clear what's going on:
if m given m = re.match(...):
I don't need to try to stuff an English description of m into its name,
because the `given` clause already describes it perfectly.
