Should I use char** argv or char* argv[]?
...function instead. So, the following are the same (analogous to the array example):
void f(void g(void));
void f(void (*g)(void));
Note that parentheses around *g is needed. Otherwise, it would specify a function returning void*, instead of a pointer to a function returning void.

What are the main purposes of using std::forward and which problems it solves?
...e-reference:
template <typename A, typename B, typename C>
void f(A& a, B& b, C& c)
{
E(a, b, c);
}
But this fails to handle temporary values: f(1, 2, 3);, as those cannot be bound to an lvalue-reference.

EDIT:
It seems I'm mistaken. Python's urlencode() (at least in 2.7.2) uses quote_plus() instead of quote() and thus encodes spaces as "+".
