Bad location info for flag warnings
When compiling program which uses parallel arrays with {-# OPTIONS -fparr #-
}, head GHC emits warning:
Warning: -fparr is deprecated: Use the PArr language instead
.
The solution is to use -XPArr
or {-# LANGUAGE PArr #-
} instead, which is not evident from the warning message.
