What about the reverse? If within takes a code block, then a closure is formed with all the outer lexicals. Your caller now pollutes the DSL?

    Well taking data from outer scope is mostly intended.

    The standard example of DSLs are embedded HTML¹, so one could mix Perl code and variables from the caller.

    DSLs are one of the hype things in Ruby, showing an adequate alternative doesn't worsen Perl's market position. ;-)

    I think of DSLs as OOP without the need to always notate the $obj_refs and ->.

    ¹) NB: I don't propagate HTML-DSLs over template engines!

    But e.g. it's thinkable to have a DSL which describes a GUI and creates either HTML or TK or Wx code.
