Comment (by Bartosz Nitka <niteria@…>):

 In [changeset:"5bc195a2caddc5c29cf24e9c731dd8d5050f2c66/ghc"

 {{{
 #!CommitTicketReference repository="ghc"
 revision="5bc195a2caddc5c29cf24e9c731dd8d5050f2c66"
 Allow top level ticked string literals

 This reverts f5b275a239d2554c4da0b7621211642bf3b10650
 and changes the places that looked for `Lit (MachStr _))`
 to use `exprIsMbTickedLitString_maybe` to unwrap ticks as
 necessary.
 Also updated relevant comments.

 Test Plan:
 I added 3 new tests that previously reproduced.
 GHC HEAD now builds with -g
