C++ is not cohesive at all

I didn't say this applies to every committee, but I do think the opposite applies to almost every "try it and see" language.

Examples of cohesive languages designed by committees would be Ada and Haskell.

Haskell is anything but cohesive, depending on which feature flags are enabled on GHC, or any other compiler.
