I have a file in which ever line of text is terminated with a number. I'd like to extract the text and the number to variables, how do I do that?

>>33
In exposed function names, it generally indicates strictness (e.g.
foldl'). In a
where clause, it generally indicates what
>>33-san said.
In variable names, it usually means the updated value of an existing variable, or a value corresponding to it in some otherway.
let a' = f a
a'' = g a'
in h a a' a''
(x,y) + (x',y') = (x + x', y + y')

_ is also an option.
