Hi,

Can you use PyPy as a direct replacement for the normal python or is it 
a specialized compiler that can only work with libraries that are 
manipulated to operate within its constraints (if it has any).

Are there any issues with using PyPy? For example, if programs are 
created under PyPy are they subtle different from normal code that would 
make the program incompatible with the normal compiler?
