Int type overflows #103

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
while adding parseInt, I got reminded that our internal Int representation 
overflows.

runk/src/Encoding.hs

The class Encoding makes an attempt to verify Integers now before they hit 
literals, but this is not used in the regular Omega parser.

Also the Int builtins wrap.

 ---> wraps :-(

So we need something like

validInteger :: Integral i => i -> Bool
