The latest Performance Tips document

http://julia.readthedocs.org/en/latest/manual/performance-tips/

says that "Uses of non-constant globals can be optimized by annotating their types at the point of use:". However, this can become tedious.

How about allowing a single type annotation in the global declaration to cover all uses in the function, eg:

global a, b::Int, c

Dup of #964 – in short, it's a planned feature.
