Bug 15791 – Cannot get a stored nested struct object from Variant

Following test case fails to compile. void main() { import std.variant; int n = 3; struct NS1 { int foo() { return n + 10; } } struct NS2 { int foo() { return n * 10; } } Variant v; v = NS1(); assert(v.get!NS1.foo() == 13); // Line 11 v = NS2(); assert(v.get!NS2.foo() == 30); // Line 13 } $ dmd -o- test DMD v2.070 DEBUG phobos\std\variant.d(755): Error: cannot access frame pointer of test.main.NS1 test.d(11): Error: template instance std.variant.VariantN!20u.VariantN.get!(NS1) error instantiating phobos\std\variant.d(755): Error: cannot access frame pointer of test.main.NS2 test.d(13): Error: template instance std.variant.VariantN!20u.VariantN.get!(NS2) error instantiating
