--- Comment #3 from Richard Smith <richard-llvm at metafoo.co.uk> ---
That may be true, but this isn't the right forum to discuss that. You can force
a conversion from a non-capturing lambda to a function pointer / function
lvalue in a number of ways, including unary prefix operator + and operator *,
so there are at least simple workarounds:

auto fn = someBool ? +[](){return 1;} : +[](){return 2;}; // ok

Clang is following the standard C++ rules here, so I'm closing this bug. If you
want to discuss those rules further, this is not the appropriate place;
std-discussion and stackoverflow would be better forums.
