Excel is a powerful and extremely versatile application, but one thing that really SUCKS about it, is that formulas are language-specific! So if using Outlook in - for example - Swedish you can't write "IF(<expression>,<then>,<else>)" but instead "OM(<expression>;<then>;<else>)". Note the semi-colon instead of comma (because in Swedish comma is used as decimal). AAARGGH! This pisses me off!2

What do you guys think about the comma expression in JavaScript? I'm aware that due to it's (to some) unknown nature that it can lead to subtle bugs, but I have at least one good use case for it and wanted to hear reasons why I shouldn't use it for similar use cases, but also what would be some other cool (not necessarily "good") use cases :D10
