You need to execute octal by using parentheses: import std.conv; enum { A = octal!"2000000"(), B = octal!"4000"() } void main() { } As the compiler has mentioned, what you have actually been doing is passing functions instead of their result when executed. What you could possibly do to avoid these parentheses is using eponymous templates.
(In reply to comment #1) > You need to execute octal by using parentheses. No you don't, this is a breaking change that needs to be fixed. octal has always been used like this.
octal isn't even a function, I thought. It uses a helper function internally, but in the end does an template octal(s) { enum octal = helper(s); } so calling it on the outside world isn't right - octal!100 should be an int literal.
Guess you are right. I'm working on this.
This problem only happens when the enum has two members. Manifest constants and single-member enums work fine. So it's definitely a bug (inconsistent behaviour between single-member and multi-member enums).
https://github.com/D-Programming-Language/dmd/pull/2277 Kind of dirty fix, but it will do it for now.
