The 'fudge' pre-processor allows per-implementation skip/todo markers
Typical usage in test file:
# tests on which an implementation dies: #?rakudo skip 'NaN not implemented' is(sqrt(-1), NaN, 'sqrt(-1) is NaN'); # test that just produce the wrong result: #?rakudo todo 'higher math' is(2**2, 4, 'power operator works');
To run a test file (and apply fudging) simply run the below from your perl6 directory:
make t/spec/S03-operators/autoincrement.t
