--- Comment #2 from Walter Bright <bugzi...@digitalmars.com> --- (In reply to Dennis from comment #1) > auto call()() Rewriting as: > auto call() and it gives the error: test2.d(8): Error: function `test2.bar` is `@nogc` yet allocates closures with the GC test2.d(10): test2.bar.f closes over variable a at test2.d(8) which is what we expect. The trouble with the template version is the semantic3() of bar() should run the semantic3() of Forward.call, which is necessary to discover that bar() requires a closure. But it does not do the semantic3() of Forward.call until after semantic3() for bar() has completed. --
