If line A is changed to "auto x = foo(1,2);" then the code compiles without
incident. This should compile with one parameter as well.
import std.typecons;
template fooRet(T...)
{
static if( T.length == 1 )
alias T fooRet;
else
alias Tuple!(T) fooRet;
}
fooRet!(T) foo(T...)(T vals)
{
Tuple!(T) ret;
static if( T.length == 1 )
return ret.field[0];
else
return ret;
}
void main()
{
auto x = foo(1); // A
}
