`eval BLOCK` is used to catch exception. It's called `try` in other languages. It's perfectly safe. `eval EXPR` is used to compile and execute code. While it does catch exceptions, that's not it's main purpose. It should be avoided as much as possible, and its use should raise big warning flags.	[reply] [d/l] [select]

`eval EXPR` ... should be avoided as much as possible To put it another way, you should use it only when you understand all the reasons NOT to. Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.	[reply] [d/l]

Exceptions aren't fast. They're exceptional.	[reply]
