This modules provides support for using JMacro with Happstack.
It provides the instance,
instance ToMessage JStat
Which will serve a
JStat value as
then called, so as to ensure the statements execute in a local scope.
An implication of this is that top-level unhygienic variables in JMacro
will not be globally available; instead, you should set properties on
JStat into a
Response, saturating the variable names with
a hash computed from the
rqUri. Unlike the
ToMessage instance for
JStat, this doesn't wrap the statements in a function and so the
workaround for global unhygienic names isn't necessary. On the other
hand, generated variable names are a bit longer.
