Abstract
The @nogc function attribute will mark a function as not making any allocations using the GC.
Rationale
Many users want to be able to guarantee that code will not allocate using the GC.
Description
@nogc goes in the same way that the nothrow attribute does, and is quite similar in behavior. It affects inheritance in that it is covariant. The name mangling for it will be "Ni". @nogc will be inferred for template functions in the same manner as nothrow is. @nogc will be transitive, in that all functions called by an @nogc function must also be @nogc.
Usage
@nogc int func(int a) { ... }
