Re: alias & local function

This one runs fine,
```
import std.stdio;
void main()
{
static int Gfunction(int x){return x;}
int Lfunction(int x){return x;}
alias gfunction = int function(int);
alias lfunction = int delegate(int);
gfunction g = & Gfunction;
lfunction l = & Lfunction;
writeln(g(1));
writeln(l(1));
}

```

it's not static so -> context -> delegate


alias myint = int;
myint i=5;
alias tfunction = int function(int);
tfunction f = & afunction;
writeln(f(1));
}
```
It gives compile error :
Error: cannot implicitly convert expression  of type 
int delegate(int x) pure nothrow @nogc @safe to int 
function(int)


add static in the second case.

I see.
Just like in Java.

I wonder why ?

alias & local function

[Alain De Vos via Digitalmars-d-learn]

The following program runs correctly
```
import std.stdio;
int afunction(int x){return x;};
void main()
{
alias myint = int;
myint i=5;
alias tfunction = int function(int);
tfunction f = & afunction;
writeln(f(1));
}
```

This does not:
```
import std.stdio;
void main()
{
int afunction(int x){return x;};
alias myint = int;
myint i=5;
alias tfunction = int function(int);
tfunction f = & afunction;
writeln(f(1));
}
```
It gives compile error :
Error: cannot implicitly convert expression  of type 
int delegate(int x) pure nothrow @nogc @safe to int function(int)
