It was pointed out by Ben Millwood on the Cafe
that there is an undocumented way to escape the
closing oxford bracket of a quasi-quote using
a backslash:
[s|This quasi-quote contains this, \|], an escaped
closing oxford bracket.|]
The backslash itself cannot be escaped in this
way:

I once spent some time and energy making [foo| bar baz |\] quux |] do
the right thing for a quasiquoter I implemented, only to discover that
GHC already supports [foo| bar baz \|] quux |]. So yes, you can escape
it.
Wow, that actually works.
That is very surprising,

Hi cafe,
in my program i use a monad of the following type
newtype M a = M (State - (a, State))
i use the monad in two different ways. The type variable a can be a
pair as in
interp :: Term - Environment - M (Value,Environment)
An environment contains local variable bindings, so no subcomputation will
ever need to return its environment.
- That is not true. A subcomputation can possible modify an environment
except the language forbids such a case.

I'd like to announce the first release of mime-mail-ses[1]. This

GHCi uses extended defaulting rules unless told otherwise, so in the
