Description

A suite of datatypes describing the abstract syntax of Haskell 98 plus a few extensions:

multi-parameter type classes
parameters of type class assertions are unrestricted

For GHC, we also derive Typeable and Data for all types.

Expressions

data HsExp Source #

Haskell expressions.

Notes:

Because it is difficult for parsers to distinguish patterns from expressions, they typically parse them in the same way and then check that they have the appropriate form. Hence the expression type includes some forms that are found only in patterns. After these checks, these constructors should not be used.
The parser does not take precedence and associativity into account, so it will leave HsInfixApps associated to the left.
The Pretty instance for HsExp does not add parentheses in printing.
