No matter how it looks to you this line means:
pull in whatever is std.random and make symbol isUniformRNG visible.

Since compiler can't know  (well that might improve but not anytime 
soon) that isUniformRNG is independent of static ctors/dtors and globals 
in that module it has to run both.

Strictly speaking what is required is breaking up modules more meaningfully.
