Maybe it's a good thing still). But I think we can't close this bug report before this little program, that shows a very basic usage of to!(), compiles with no errors or warnings: import std.conv: to; void main() pure { string r = to!string(to!real("2.5")); } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=7438 PDT --- I'd be very tempted to argue that that should be a separate bug. There's a big difference between std.conv.to should always be pure for everything and std.conv.to should be pure when converting to strings. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I would even argue that it should be safe. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=7438 PDT --- Whether std.conv.to can be safe or pure depends entirely on what you're converting. For all of the built-in types, it should be safe and pure, but once user-defined types enter the mix, it depends on how the user-defined types are defined. A lot of the underlying stuff which relates to arrays (like appender) hasn't been able to be pure in the past (I don't know quite where that sits now though), making it so that stuff like std.conv.to!string(10) hasn't been able to be pure even though it should be. So, odds are that the lack of purity or safety in std.conv.to isn't std.conv.to's fault at all. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=7438 --- yes it turtles down. Just to see how hard it breaks I mark some pure. I stopped somewhere in format. So looks like not so much fun. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
