https://issues.dlang.org/show_bug.cgi?id=13451 --- Comment #2 from briancschott@gmail.com --- https://github.com/D-Programming-Language/dmd/blob/master/test/runnable/funclit.d#L258 I would not be surprised if it started off as an oversight and was then added to the test suite. We should never break the promises we never made, right? -- |

Is it intentional, or is it an oversight in the implementation? It's a hold-over from the other function literal syntax: auto fp = function int(int a) { return a; }; It's just as useful whether it's using lambdas or the old syntax, so I suggest we reconcile the grammar with DMD in this case. -- |

Lambda: function Type(opt) ParameterAttributes => AssignExpression delegate Type(opt) ParameterAttributes => AssignExpression ParameterAttributes => AssignExpression Identifier => AssignExpression -- |
