For language manipulation features like AST macros hooks into error and warning
at the compiler may add value in the future.
Proposal is to add pragma(error,) and pragma(warning,).
They should behave as pragma(msg,) except be hooked into the compilers warning
and error systems.

There is currently static assert(0, ) which does do close to what
pragma(error,) proposed does however it also does prepend "static assert" to
the output. Because of this the purpose to me is different.
However if pragma(warning,) was to be added and not pragma(error,) it would be
confusing for new users to not have it all in one place.
