This version introduces variable visibility.

(You need to compile the Erg file by running erg --mode compile [file].er before executing the Python file.)

A Chinese translation of the error messages was then added by a volunteer. If you want to use this, please install the Chinese version as cargo install erg --features simplified_chinese (or cargo install erg --features traditional_chinese).

Full Changelog: v0.2.2...v0.2.3

v0.2.2

In this release, type inference for general polymorphic types can now take variance into account.
For example, since the Seq(T) type is covariant with respect to T, Range(T), which implements Seq(T) as a trait, for example, is recognized as a subtype of it.

v0.2.0

With this release, some of the APIs of the math and random modules of Python are now available.

In addition, several type inference bugs have been fixed.
