All Haxe code is organized in modules, which are addressed using paths. In essence, each .hx file represents a module which may contain several types. A type may be
private, in which case only its containing module can access it.
The distinction of a module and its containing type of the same name is blurry by design. In fact, addressing
haxe.ds.StringMap<Int> can be considered shorthand for
haxe.ds.StringMap.StringMap<Int>. The latter version consists of four parts:
If the module and type name are equal, the duplicate can be removed, leading to the
haxe.ds.StringMap<Int> short version. However, knowing about the extended version helps with understanding how module sub-types are addressed.
Paths can be shortened further by using an import, which typically allows omitting the package part of a path. This may lead to usage of unqualified identifiers, for which understanding the resolution order is required.
