This module contains a parser for our intermediate representation (IR).

The intermediate language is usually not parsed directly. It is more common for another language (e.g., Haskell) to be parsed and converted to out intermediate language. The main purpose of the IR parser is to easily construct AST nodes in unit tests without making the tests dependent on some front end for the construction of the AST.

The syntax of the intermediate language is based on Haskell. However, there is only very little syntactic sugar. For example, there are no infix operations, all applications are written in prefix notation. Since the unary minus is actually syntactic sugar for negate in Haskell, there is also no unary minus in the intermediate representation. Furthermore, the intermediate language does not implement Haskell's layout rule.

The parser does not support source spans at the moment, all generated nodes are annotated with NoSrcSpan.
