I can't find any documentation for is_lambda_expression...though I didn't look very hard...is it part of the public API?
I do not believe it is in the documentation. But since it's part of the public interface shouldn't it be required to work correctly?
Can you point to something that indicates it is in fact part of the public interface? If it's not documented, I don't know what properties is_lambda_expression has and what guarantees it makes. Its name suggests some, I admit, but who knows what the author's intents were? Without some additional documentation, the code defines its behavior, hence I'd say it's tautologically correct :) I can sympathize if you think the above implies this metafunction should be an auxiliary or detail namespace; I would agree. Is this just an FYI, or are you genuinely in need to detecting Boost.MPL lambda expressions? - Jeff
