It won't work with control strings as plain strings -- what would the
type of Stats.linear_regression be ? Functional unparsing solves the
problem by using values of a particular type and combinators to
represent the control string (you can actually see it as directly
manipulating the abstract syntax tree of the corresponding control
string).
Have a look at Olivier Danvy's paper [1]. You may also be interested
in language embedding in general, see this message [2] for a reference
and an example.
Best,
Daniel
