Summary0004762: ?? is not used at all, but registered as a lexer token
DescriptionThe keyword "??" is defined as QUESTIONQUESTION in lexer.mll, but it is never used in parser.mly. As a result, we cannot define the binary operator ?? even though it is not harmful at all.
TagsNo tags attached.

?? was used to handle errors in stream parsers.

I don't know if it is still necessary with the new Camlp4 implementation...

?? is no longer considered as a token. It can thus be defined as an operator. However, note that it defines a prefix operator, not a binary one.
