Module Suffix is added in rec module even if type with the same name is generic #5794

There's no clash in names between a module and a generic type and therefore no Module suffix is needed. That was implemented in #1772 -- but only for normal modules. Inside rec modules the Module suffix is still added.

Repro steps

  module rec M

  type A<'a> = A of 'a
  module A = begin end

Expected behavior

Module A is still named A after compilation.

Actual behavior

Module A gets renamed to AModule.

Known workarounds

None (probably besides using a static class instead of module...)
