''(page spawned from [incr])'' ---- [Martin Lemburg]: I love readable code and using ''decr var 1'' is more readable than ''incr var -1'', or am I wrong? [RS] In matters of taste, one self is mostly right, and everything else appears to be wrong;-) I think the philosophy for not introducing a ''decr'' command analog to [incr] was that ''[incr] -'' does the same job, and makes the language smaller. A smaller language may be better readable than a bloated one, because the reader can more easily have full grasp of the language. On the other hand, you extend the language everytime you write a [proc]... The tradeoff between personal requirements (which might lead one to write a ''decr'' proc) and simplicity (which tries to avoid too many extensions to the language, and also has to do with efficiency) has to be part of every design decision. I prefer (of course) shorter code without many extensions. When I started Tcl, I was very proud that I could create language elements like [lassign], to spread a list to scalar variables, but over time I've come to think that foreach {a b c} $list break is readable (if one knows how to read it) and standard Tcl, while lspread $list to a b c (that's how my version looked) requires either reading or "intuiting" the definition of ''lspread'', one costing time, the other possibly misunderstandings, so I don't do such things no more.
