Issue ID: 15780 Summary: CTFE foreach fails with tuple Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: regression Priority: P1 Component: phobos Assignee: nob...@puremagic.com Reporter: jbc.enge...@gmail.com This code: ``` import std.typecons; void foo(alias fields)() { foreach(i, field; fields) { enum string a = fields[i]; // OK enum string b = field; // not OK with 2.069.2 ??? } } void main() { foo!(tuple("H", "I", "J"))(); } ``` Builds with DMD 2.068.2. Fails with DMD 2.069.2, and fails with DMD 2.070.2: foreachTuple.d(6): Error: variable field cannot be read at compile time foreachTuple.d(6): Error: variable field cannot be read at compile time foreachTuple.d(6): Error: variable field cannot be read at compile time foreachTuple.d(11): Error: template instance foreachTuple.foo!(Tuple("H", "I", "J")) error instantiating I believe this is a regression.
