Exception

The exception class makes errors easier to parse with where and what members, as opposed to having a string with both.

For ease of use, constructing an exception automatically throws it.

try
    new exception("Not implemented")
catch e then
    print(e) -- same as error("Not implemented")
    print(e.what)
    print(e.where)
end

Output:

script.pluto:2: Not implemented
Not implemented
script.pluto:2
