You don't. parse requires that you pass it a variable.
std.conv.to does not take its argument by ref, so you can use
that instead, but it converts the entire argument instead of
just the front portion that matches the requested type. So, if
you're trying to convert the entire argument, then you can use
to, but if you're trying to just convert the front, then you
have to use parse, and that means passing a variable.
