--- Comment #1 from Roman <freeslav...@gmail.com> --- Note that there's another error that precedes the crash ../inilike/source/inilike/file.d(185,33): Error: no property 'map' for type 'ByNode!(Node)' [../inilike/source/inilike/file.d(183,19)] byNode _error_ While import std.algorithm : map is clearly here. There's another function that has the same import, byEntry. If I move such import into the scope available for both functions there's no error. --
