Thanks, cutting it down helps ENORMOUSLY.
But it looks to me as though what you're seeing is just the compiler internals.
Constant folding of  "Inside: " ~ axisFilterLoop!(S)() 
can only happen AFTER axisFilterLoop has been instantiated. When you uncomment
the "Outside" pragma, you're forcing the compiler to use instantiate it.
Without it, it happens to use another order, where it tries to axisFilter1
first, then realizes it needs to do axisFilterLoop first. So it fails, *but it
outputs the pragma first*.

It didn't do this in 1.050, but did in 1.051. But it looks as though it only
affects pragma(msg), in which case it's a minor issue.
