[back to package description]

matchable

This package provides a type class Matchable, which represents zipMatch operation which can zip two values.

zipMatch operation can fail, and it returns zipped value wrapped in Maybe. Specifically, zipMatch returns zipped value if and only if two arguments have exactly same shape.

Example

>>> zipMatch [1,2] ['a','b']
Just [(1,'a'), (2,'b')]
>>> zipMatch [1,2,3] ['a','b']
Nothing

See example also.
