Running Main without any arguments via Hat gives me a trace, and the error message:
Error: pattern-match failure in do expression
Running hat-stack Main.hat gives me:
Tracefile "Main.hat" contains no reference to a program error.
Very strange. The tracefile contains the error message (at the end), and an explicit reference to it (in bytes 8-11). But it contains no reference (in bytes 4-7) to the expression that triggered the error, and so hat-stack quite reasonably complains. It looks like the library code to trap the error and tidy up the tracefile might have a bug. Regards, Malcolm
