i've always wondered why input's default behavior was like this. a 
better function name would be "execute_arbitrary_code". if the user 
wants a certain type of data, 10 out of 10 times they can just convert 
it to the desired type...

input = raw_input #BLARGH
float_val = float(input('Enter A Float'))
int_val = int(input('Enter an Int'))
