That's not guard clause style [1][2].

Neither was your original example.
"A method has conditional behavior that does not make clear what the
normal path of execution is"
void bar (T ...) (T args) if (T.length == 0)
{
return;
writeln (args [0]);
return bar (args [1 .. $]);
}
void bar (T ...) (T args) if (T.length > 0)
{
writeln (args [0]);
return bar (args [1 .. $]);
}
(you meant T I suspect, as args is a runtime thing, but T is compile
time, just like static if).
