Feedback for nullc Idea

Hi PHP folks, I submitted a proposal on Monday that received no replies.  The idea was about adding a functional construct nullc() that could act as an inline null coalesce for a variable.  That task is currently not possible in a nullc() user function, but instead requires an expression like ($var ?? null) with mandatory extra parentheses.  A functional expression could make this less prone to mistakes.  It would also avoid concerns with alternatives such as unary operators. Any feedback on this idea would be appreciated. ------------- Robert Chapin
