Could you help me understand this better? For example, if you
have this line in the Python program:
foo = 'some text'
bar = {'apple':'fruit'}
If the interpreter can determine at runtime that foo is a string
and bar is a dict, why can't the compiler figure that out at
compile time? Or is the problem that if later in the program
you have this line:
foo = 12
now foo is referring to an integer object, not a string, and
compilers can't have two names referring to two different
types of objects? Something like that?
I in no way doubt you that this is not possible, I just don't
understand enough about how compiling works to yet "get"
why dynamic typing is a problem for compilers.
Thanks.
