Thoughts? Other ideas?
how would this be different then limited imports such as:
import std.random: isUniformRNG;
?
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.
