No.  While these are common idioms, I have not been willing to invent
syntax to encapsulate them.  What you're looking at is something like
ksh coprocs, where Korn invented a syntax to specify them (|&) and
added options to various builtins and created new redirection syntax
to use them.

I prefer the more general composition of basic features.
