A little shorter code, that requires less changes:

assert(a.length, ctEval!("Attempting to fetch the front of an empty array of "
~ T.stringof));

Where ctEval is a very small construct that should be added to Phobos that forces the evaluation of an expression at compile-time.

I suspect the error message is already being computed statically thanks to constfolding, it just happens after @nogc inference has been run.

Apparently, the underlying dmd issue has been fixed/implemented. A pull request to add @nogc to the various functions: https://github.com/D-Programming-Language/phobos/pull/3219

Commit pushed to master at https://github.com/D-Programming-Language/phobos

https://github.com/D-Programming-Language/phobos/commit/0842fc7841b9c3db558681717c2d8b4da1479ce6 @nogc for std.range.primitives.{empty,save,popFront,popBack,front,back}

Excluding the UTF-decoding variants, because those throw GC allocated exceptions.

Makes sure that issue 12666 - "@nogc std.array.front, popFront, and more" stays fixed.
