Description of the change
Allow tabs as indentation in purescript source files. Implemented as suggested by @rhendric in this comment. Only difference is that i didn't add
HDelta|VDelta
, i addedPosDelta
, which is asVDelta
was described. I found it redundant to have aHDelta
when that could instead be represented as a "VDelta
" with 0 lines and 0 tabs.I was unsure about the usage of
!
andUNPACK
pragmas in data declarations, so let me know if any of those should be done differently.Marked as draft because i have not implemented tests yet, but the code itself is ready for review.
Closes #3939
