Compilation error with a 'strong typedef'

[psiha]

MRE https://godbolt.org/z/fE1ceqehP

To make it compile, either/at least one of:

• switch boost::container::vector back to std::vector (it has to be exactly that, no other container will work)
• replace the strong typedef with a weak one
• simplify the parser to just ( bp::short_ % ',' ).

Do you have a proposed fix? Looking at those errors, it looks like you're running afoul of language rules, not library problems. If you make a typedef instead, things work -- as you noted. I don't know of a way to test whether a destructuring will be well-formed without using something like statement expressions (which I think we'll get in C++29, but don't have now).

My current thinking is that this should just be mentioned in the docs.
