intuitive, since they're used to thinking of arrays as pointers.
Are they used to disregard value types too? I don't see it working in C:

Not exactly. Because C arrays are pointers, it does work that way:
void foo(int c[])
{
if(c) {...} // same as if(c is null)
}
But C doesn't have any other possible piece to check, as the length of
the array is not part of the code.
The closest equivalent is C++ vectors, and if(someVector) doesn't work.
