For my code the functions have to be declared within the main function
rather than being at module level.

Hi,
I just noticed ufcs does not work with alias. Is this limitation
needed?
void foo(int a) {}
void main()
{
alias bar = foo;
3.foo();
3.bar();
}
Last line fails with "no property 'bar' for type int.
Should I open an enhancement request?
