OK guys! Exported functions are widely used by experts, I get it now.

Sure, the mechanism need not be documented, if it didn't matter on the
interface level. But it does. In particular,

    % pat='() { $:*;}' bash -c 'tr "$pat" _ <<< "(x){1}"'

(This is bash 4.3.25)

This is not the best example, but you get the idea.

Perhaps you have plans to change the implementation?
