pg: I disagree -- I still find it puzzling that you made this design decision about Arc. I program mostly in Common Lisp and I use very few keystrokes. SLIME+paredit+redshank in Emacs allow me to do structured code manipulation with impressive dynamic completion (as in m-v-b<TAB> -> multiple-value-bind).

In spite of my RSI problems I don't feel a need for more succinct naming. Succinct languages, yes, abbreviated names, no.
