// test1.c typedef struct { int i; } S1; const S1 unused; S1 s; void fn() { int i = s.i; } // Error: need `this` for `i` of type `int` // test2.c typedef struct { int a,b; } S2; const S2 aaa = { 0,0 }; S2 bbb = { 0,0 }; // Error: 1 extra initializer(s) for `struct __tag3` both bisected to https://github.com/dlang/dmd/pull/13990

oh well, it isn't.

increasing the importance since this would become a regression in v2.100.0 compared to v2.099.1 if there's no immediate fix available, then i'd prefer if the PR that caused this was reverted since the bug(s) it fixes weren't that common compared to this one
