I found another strange test failure on rakudo-j related to the use of prefix:<++>: The test in integration/weird-errors.t (which I fudged with roast commit ca3abdefb1) started to fail with rakudo commit e2fcdf2702.
The test in isolation works fine, but the failure happens in combination with another -- unrelated -- piece of code from the same test file. I golfed it down to this: ==== $ cat 128123.p6 q:to/FOO/; FOO my $bar = 0; ++$bar; ==== Running this code dies with "Expected a native int argument for '$a'". All of the following changes make the code work: * remove the indentation of the heredoc (line 2) * use native type in line 3: my int $bar = 0; * don't assign to $bar in line 3: my $bar; * use postfix:<++> in line 4
