[Haskell] looking for reference to wadler's (?) law of language design

this is slightly off topic - I am preparing for a lecture on domain specific languages and I try to track down the source and original version of (what I recall as) Wadler's "law" of language design, "the energy spent in designing a programming language goes into, in increasing order of effort: semantics, syntax, syntax of comments". -- -- Johannes Waldmann, Tel/Fax: (0341) 3076 6479 / 6480 -- ------ http://www.imn.htwk-leipzig.de/~waldmann/ ---------
