GHC seems to re-read source of module to produce fancy error msgs
I had a module with unused name txFees in it. I started compilation and in the same time edited code by renaming txFees -> _txFees.
I got the following message:
warning: [-Wunused-matches]
Defined but not used: ‘txFees’
|
40 | } _txFees
| ^^^^^^
<no location info>: error:
Failing due to -Werror.The screenshot is in the attachment. Notice that message part is about old code (txFees), and preview is about new code (_txFees).
