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

[Johannes Waldmann]

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".
