Nicholas Wilson <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] | |m --- Comment #2 from Nicholas Wilson <[email protected]> --- The usage of is(typeof(parse!T(value))) follows a common pattern in phobos: namely to specify external dependencies of the function. (e.g. `all` has `is(typeof(unaryFun!pred(range.front))` in its constraint) toImpl uses parse and so specifies that in its constraint. This has the obvious effect of invalidating the template's candidacy which is needed because D doesn't do SFINAE. This is not a regression, just an unfortunate side effect of the above. On that note, my DIP[1] would make it immediately obvious that parse!T(value) is where the problem lies. [1]: https://github.com/dlang/DIPs/pull/131 --
