in reply to Regexp do's and don'ts
In my (somewhat devalued) opinion, there is only one DO... and one DONT... worthy of note.
- DON'T tell others what they should or should not do.
- DO explain to others why you choose to do (or not) certain things (in particular ways).
For bonus points, also explain why you (or others) might choose use the proscribed behaviour (or not use the advised behaviour) under some circumstances. Make particular emphasis upon explaining the deciding factors that would sway your decision against your norm.
Examine what is said, not who speaks.
