Documentation
This datatype is the result of a parser.
First it stores a sequence of warnings.
Warnings are for corruptions of the input which can be fixed.
After encountering a series of warnings,
there is finally an end,
either a successful one, with the result as (Right result)
or an eventual non-fixable problem indicated by (Left errorMessage).
