Issue ID: 15323
Summary: Module.members and .deferred3 should use data
structure with fast lookup
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]

On a moderately sized build (yes, per-package), iterating Module::members and
Module::deferred3 over and over again to check whether they already contain a
given template instance takes up a noticeable amount of time (about 5% and 3%
of the total compilation time).
The arrays should probably be replaced by a structure with sub-linear lookup
for an easy compile-time win in template-heavy projects.
