What are some common mistakes when using lambda and proc in Ruby?

Some common mistakes include confusing the return behavior of lambda and proc, and not understanding argument handling.

Can you explain the difference in return behavior?

Sure! A lambda will return from the lambda itself, while a proc will return from the enclosing method.

What about argument handling? How do they differ?

Lambdas enforce the number of arguments, while procs do not. This can lead to unexpected behavior if not careful.

Can you give an example of when this might cause an issue?

Certainly! If you pass too few arguments to a lambda, it will raise an error, but a proc will just assign nil to the missing arguments.
