To reproduce the format issue, try to print the struct with

I implemented the compile time format string checking by
evaluating `format(fmtStr, Args.init)` at compile time and
seeing if an exception was thrown. So the above problem could
be worked around by guarding the invariant test with a check
that CTFE is not active.
Note that I've gotten a fix for this merged that doesn't break
format use in ctfe: the compile time format string check simply
writes into a NoOpSink, and the formattedWriter detects the
NoOpSink and skips the toString.
So that's good now.
