hi,
i tested the following code in Hugs:
{{{
patternMatchingWorks1 = case '\x4ff' of '\x4ff' -> True
patternMatchingWorks2 = case '\x500' of '\x500' -> True
patternMatchingWorks3 = f '\x4ff' where f '\x4ff' = True
patternMatchingWorks4 = f '\x500' where f '\x500' = True
patternMatchingWorks5 = (\'\x4ff'->True) '\x4ff'
patternMatchingWorks6 = (\'\x500'->True) '\x500'
}}}
and got the following output:
{{{
Main> :load "M:\\haskell\\sources\\WinHugsPatternMatchingBug.hs"
Main> patternMatchingWorks1
True
Main> patternMatchingWorks2
Program error: pattern match failure: patternMatchingWorks2_v1621 '\1280'
Main> patternMatchingWorks3
True
Main> patternMatchingWorks4
Program error: pattern match failure: patternMatchingWorks4_v1623 '\1280'
Main> patternMatchingWorks5
True
Main> patternMatchingWorks6
Program error: pattern match failure: patternMatchingWorks6_v1627 '\1280'
}}}
i tested it with hugs.exe and winhugs.exe (September 2006 version, i.e.
the
most recent according to the download page) on Windows XP Professional,
both
give the same result, while ghc gives the correct result.[[BR]] Pattern
matching
seems to fail for all Chars with codepoint >0x4ff. i understand that Hugs
doesn't fully support Unicode, but is this intended behaviour? If so,
please
mention it on the "Hugs Bugs & Features" page.
