[LLVMdev] What is a FunctionType really?

[edA-qa mort-ora-y]

This may sound weird, but what exactly is a FunctionType? That is, in
terms of memory, or underlying value, what does the FunctionType
actually represent. At first I though it might be a pointer, but it is
not -- since you have to wrap a PointerType around it to use as such.
Can a FunctionType value actually exist, or is strictly an abstract
concept? In particular, can I actually directly define some type to be a
function type, or must I always declare it as a pointer to that type?
