George Zipperlen, speaking at you:
New to Rebol, thanks to @hostilefork presentation at Philly Lambda functional programming meetup, and invite to Rebol  conference.
Started out in pure math, first language APL -- Just get things done !
Rude awakening to FORTRAN
Ruder awakening to PL/I and JCL
Systems programming in Pascal, and assembler because Pascal forbids you to...
C / Unix / shell, sed, awk, perl, TCL -- more getting things done and shooting myself in foot.
SQL, MatLab, S/R -- powerful, but slow and clunky
CommonLisp for natural language processing -- Ugh!
Smalltalk for digital telephony -- loved it
C++ and Java -- rude awakening from the pleasures of object oriented programming to obsessive inheritance hierarchies. Revenge of the Pascal nanny
Python, somewhat elegant. Machines now fast enough that it's usable...
