Add StringPrimL to template-haskell
In designing a template haskell lexer, you cannot get the same performance as alex, due to the fact that you cannot encode a "string"#
literal to house the lookup tables for the encoded lexer.
Proposal: add "string"#
literals to template-haskell
as StringPrimL
(or another suitable constructor) to Lit.
Then the quasiquoter can emit a data type that contains Addr#
references to the link-time-locatable "string"#
s permitting constant folding and inlining away the particular link time choice of Addr#
.
