I just came across this. Can't believe there's not been more
people finding this:
char[] buf = new char[100];
buf.formattedWrite("This is a number: %s", 5); // Error cannot

OK, challenge accepted!
buf[0 .. myName.length] = myName[]; // Hey phobos, look, this
is easy!

"Use .representation" would be the official answer for the second
hack.
But this should absolutely work. It looks this looks the same
thing as

18472 broke compilation of DCompute under -betterC when upgrading
LDC to a newer DMDFE, I "fixed" it by not compiling with -betterC
but then Mike Franklin (thanks!) discovered the above error after
fixing the -betterC side of things.
I'm going to be extremely unhappy if I can't compile dcompute at
all with the latest LDC.
IMO this is a priority 1 regression.
