[fpc-pascal] assigning a local function to a var

"One can assign the following values to a procedural type variable:
1. Nil, for both normal procedure pointers and method pointers.
2. A variable reference of a procedural type, i.e. another variable of 
the same type.
3. A global procedure or function address, with matching function or 
procedure header and calling
convention.
4. A method address."

Note "A GLOBAL procedure or function ... "

This is for a reason - think what would happen if you were able to a 
local procedure to a global variable!

FWIW the same is true of Delphi.
