I'm going to assume this message was cut-off otherwise an example
illustrating the issue would have been a definite help. If you aren't
using -fglasgow-exts then I can't think of anything that would break
whatever, however in 6.0, probably the most major thing in 6.0, is
Template Haskell which takes some lexemes. If you have a list
comprehension like [d|d<-ds] then you are going to have issues as '[d|'
is a lexeme in TH. Others include, '$(', '[|','|]','$x' where x is some
variable
