Comment:
Another use for this would be for creating custom quasiquoters with
antiquoting. Say, to create a custom list quasiquoter:
{{{
[list| x^2+y, 3*z |]
}}}
the quasiquoter needs to parse antiquoted expressions such as {{{x^2+y}}}
and {{{3*z}}} into TH abstract syntax. Current quasiquoters mostly do this
using haskell-src-exts (via the haskell-src-meta library), but it would be
neater just to return a {{{RawE antiquoted_stuff}}} expression.
