matchable
This package defines a type class Matchable,
which provides zipMatch operation for zipping two values of a
container type.
The zipMatch operation can fail. It returns the zipped value wrapped
in Maybe. Specifically, zipMatch returns zipped value if and only if two arguments
have the exactly same shape.
Example
>>> zipMatch [1,2] ['a','b']
Just [(1,'a'), (2,'b')]
>>> zipMatch [1,2,3] ['a','b']
Nothing
