# So this is how the 'calc' command works:
# First, we make a nice little safe environment for evaluation; basically,
# the names in the 'math' and 'cmath' modules. Then, we remove the ability
# of a random user to get ints evaluated: this means we have to turn all
# int literals (even octal numbers and hexadecimal numbers) into floats.
# Then we delete all square brackets, underscores, and whitespace, so no
# one can do list comprehensions or call __...__ functions.
