Re: Idea: Standard way to negate special targets

[Michael Livshin]

Or!
How about a general syntax for canceling prerequisites (not just for
special targets)?  Say, "!:" (inspired by "&:")?

Then you'd just say ".ONESHELL!: my-tricky-target".  More verbose than
"my-tricky-target: ! .ONESHELL" or whatever,
but seems more robust to me (and more general, although I couldn't off
the top of my head say when one would want to
cancel any normal prerequisites...).

Cheers,
