Plenty of 'wait-a-bit' thorns awa= it those who think otherwise. Yes, I could just write in assembly, but that would remove the efficiency o= f my creativity as a programmer :) I choose my tools to assist me in both b= eautiful expression of the idea that others can read (and as Wirth points o= ut in Programming in Oberon, Assembly is unreadable) and to assist me in co= rrectness. > A computer is a tool. A language is a tool. When you know your tools you = can make wonders. When you dont . . you might need a few lessons of that mo= st detested computer scientist Prof Wirth. :) Not sure I got that one. I assume first I was wrong and the tool had a diff= erent idea than I, as was evident. Not sure though how Wirth fits in, since= in the next line in the Wirth text I just mentioned, he points out a progr= am that is not readable by humans is worthless.

I would say that concatenation operations with order of evaluation not sign= ificant is an unexpected gotcha for most human readers and so a language sh= ould not tolerate it. David Botton
