In D often heap allocations are the main cause of low performance code, or they
may cause less deterministic code (in video games, etc).

A function annotation named "@noheap" may help (similar to @nothrow), it makes
sure a function/method contains no heap allocations (new of
arrays/objects/structs, array concat, array append, closures, associative array
insertions, malloc/realloc/calloc, and so on, but not alloca()) and doesn't
call other things that perform heap allocations.
