What is going on with UFCS and foreach?
foreach(i;0..5).writeln;
This prints five line breaks.
foreach(i;0..5).i.writeln;
This will not compile.
foreach(i;0..5).writeln(i);
This writes out 1 to 4 on separate lines. Is this supposed to
work? I thought a.b would be rewritten to b(a) with UFCS but
writeln(foreach(i;0..5)) is nonsensical and does not compile
and should be the same as foreach(i;0..5).writeln;
The compiler interprets it as a foreach without curly braces.
With curlies it would look like:
foreach(i; 0..5)
{
.writeln();
}
In this context the dot means the writeln lookup should happen
from the module level scope.
