Hello. I hope you are all having a nice christmas pre-time.

I'm writing a function that takes a list as argument. It's not a simple list, it's actually a list of lists, a data structure I made. We have something like this:

{testee, {..}, {..}}

In my function, I try to test the type of data of "testee". I want to know whether it is symbol or integer. The problem is...:

In[95]:= Head[1] == Integer
Out[95]= True
(*This one is ok, but then...*)
In[96]:= Head[1] == String
Out[96]= Integer == String

Why won't he give me "False"? Have you guys run into this before? :/

Thank you very much in advanced.
