Issue ID: 16208
Summary: moduleinfo importedModules contains needless
duplicates
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P1
Component: dmd

When trying to debug a module cycle issue, I stumbled across the realization
that each time a module imports another module, that reference is added to the
list of imported modules, even if it's already there.
The compiler should eliminate these duplicates, as it slows down runtime
startup during module cycle detection, and bloats the executable.
Especially when idiomatic D code is supposed to import locally only when
needed. Each of these local imports adds another reference.
