Need a str/boolean check

[madscatt]

Sometimes a variable is defined as a string but the programmer thinks it is a boolean. If one uses statements like

`my_boolean = "False"'

if my_boolean:

will evaluate as True as the my_boolean string exists. We should consider more robust usage of booleans to avoid these types of mistakes.

Note that

my_boolean = ""

if my_boolean:

will evaluate as False.

In Python 2.7 booleans are subclassed from ints. True and False are not constants!

Perhaps name all booleans with a suffix _bool e.g.

some_variable_bool

instead of

some_variable
