Make Exception datatypes into newtypes
Certain instances of Exception in base are datatypes with only one argument:
data RecUpdError = RecUpdError String
data RecConError = RecConError String
data RecSelError = RecSelError String
data PatternMatchFail = PatternMatchFail String
data NoMethodError = NoMethodError String
data AssertionFailed = AssertionFailed StringWhy not make these into newtypes?
