Somehow let users catch errors in function evaluations

[nabenabe0928]

Basically, this part squeezes errors caused in function evaluations, so it is hard to debug.

I don't know what version and code was doing that but the error handling has gotten a lot better recently and now actually shows you errors that happened. You can always put a try: catch: in the target function and report back the values you would like to.

However, the try: catch was possible before, was there something else you meant?
