DMD's optimizer is the whipping boy around here, but to be fair, it is
poor only when it comes to aggrssive inlining and optimizing loops.

You can look at the generated code using the Compiler Explorer at

The `static if` is guaranteed to be evaluated during
compilation. That means, `foo!y0` effectively becomes this:
auto foo(int rt) { return rt + 1; }
There is no such guarantee for `foo(rt, y0)`. It doesn't matter
that y0 is

I am curious how ctfe and static ifs interact. In particular, if
an enum bool passed as a template parameter or run-time one will
turn an if statement into something like a static if statement
(perhaps after the compiler optimizes other code away). In the
code below, I am a function that takes
