Added RFC on dereferencing *T

I'm not in favour of this. Unsafe code is already hard to get right, let alone adding new sources of non-explicitness which can't easily be checked at the source level.

[huonw]

This seems like the more fundamental problem, and the one that would fix your issue: Rust doesn't offer flexible enough control over statics to be able to use safe(r) wrappers for this use case.

(That said, it is just essentially just 8 bytes in rodata, right?)

[farcaller]

It's 4 bytes in rodata, four more instructions to fetch the address from there at each call invocation. That isn't critically significant, but easily adds useless weight to binary.

Deprecating this in favour of #44
