I've grown accustomed to words that sound or look the same meaning different things depending on context or the language being used (not that I'm this language wizard, it's just a byproduct of the process I went through to stop giggling every time I counted to 6 in German). So, when I'm using almost any other programming language, "declaration" means something along the lines of "bringing into existence". In Perl, I use "declaration" closer to the common English usage, "statement of fact".

• "We are in package Foo now."
• "$bean is mine. Mine, I tell you!"
• "$foo is ours, not mine."
• "There's a subroutine called 'as_string', and this is what it does..."

Admittedly this is very unscientific - perhaps even dangerously inaccurate in a classroom. Folks around me generally know what I mean, though. I guess in general usage I lean towards pragmatic rather than pedantic :-)
