Hello, My code: > import std.string : join; > > enum Key : string > { > First = "qwerty", > Last = "zaqy" > } > > struct Qaz > { > enum text(alias Values) = Values.map!(value => "bool has" ~ value ~ " = false;").join(); > } > > //enum text(alias Values) = Values.map!(value => "bool has" ~ value ~ " = false;").join(); > > void main() > { > pragma(msg, Qaz.text!([Key.First, Key.Last])); > } During compilation I get: > /dlang/dmd/linux/bin64/../../src/phobos/std/algorithm/iteration.d(475): Error: this.__lambda2 has no value > onlineapp.d(33): Error: template instance `onlineapp.Qaz.text!(["qwerty", "zaqy"])` error instantiating > onlineapp.d(33): while evaluating pragma(msg, (Qaz).text!(["qwerty", "zaqy"])) If I uncomment that line and use > pragma(msg, text!([Key.First, Key.Last])); then compilation is passed. What happens? |
