How to translate these attributes to Adept?

[ghost]

__attribute__((pure)), __attribute__((used)) and __attribute__((weak)).

[IsaacShelton]

For creating C bindings,

__attribute__((pure)) can be ignored.

__attribute__((used)) can be ignored.

__attribute__((weak)) can be ignored as well.

But if you're writing the functions inside of Adept,

__attribute__((pure)) can be ignored.

__attribute__((used)) can be used as external.

__attribute__((weak)) is not supported
