Lambda's are delegates and delegates have a "this" type of
pointer. I would like to get at it inside the lambda to check
for some things. I'm doing some funky stuff. I'm not concerned
about the scope or what this actually pointers to or anything
like that, just need it's value for debugging.
No, delegates do not have a "this" type of pointer. "this" is an
implicit function parameter in a class or struct member function.
Delegates have no such thing. The only generic way I know of to
get at a delegate's function pointer inside the implementation is
to explicitly add the pointer type to the parameter list as part
of the declaration and pass it as an argument when you call the
delegate.
