Just stumbled over this "issue" yesterday, so I'm quite happy to see that patch! |
|
Looks pretty useful, and I don't think there can be any drawback. Leaner types make GADT easier! |
|
Nice and useful. I was afraid that you removed all the FWIW, I think this patch is good. |
|
I initially wanted to make a specific testsuite for desugared syntaxes, to avoid the problem you considered (removing the initial non-sugared syntax that could somehow break without notice), but I found out that the property I wanted to check (that parsing then pretty-printing preserves the sugar, or absence thereof) did not hold at all for common situations such as |
|
If we want to test sugared syntax, perhaps a good test would be to print the desugared sugared version, and print the desugared not sugared version and verify that the printed results are identical (even if it is different of both input). Then in all the other tests we can use one or the other without consequence. |
Fix handling of applicative paths in equality checking for type constructors.

Merged in trunk. |
More accurate benefit
Added missing function for native code.
