One may say that this effect may be avoided by remembering to carefully localize all package variables in all called functions, Unintended side effects are unintended side effects:
The problem has nothing to do with aliasing and everything to do with not localising! Your previous quote is better stated as: "don't use code that uses globals for no good reason.". Which is doubly true for code that fails to localise its use of globals. a healthy dose of paranoia. Sorry, but I will always consider 'paranoia' in programming -- and pretty much everything else for that matter -- with exclusively negative connotations. The teaching of 'paranoia', rather than 'knowledge', in an attempt to avert disaster, is always a counter productive and ultimately futile process. With paranoia, one can only hope to avert bad consequences; with knowledge one can know you have. Don't hope, know! With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
