• authorized malicious joy over a missing operator

    From Michael Uplawski@21:1/5 to All on Sun Jan 1 10:24:56 2017

    This morning I was tracking a long-standing bug in one of my “programs”
    and arrived at improving its performance. Under some conditions,
    however, I was confronted with an undefined method error for an object,
    that I do not call the said method on... 8-/

    In the end, I found an if-clause with a missing '&&' operator.

    In IRB, it looks like this:
    irb(main):001:0> value = "egalomat"
    irb(main):002:0> value ! value.empty?
    NoMethodError: undefined method `value' for main:Object
    from (irb):2
    from /usr/bin/irb:11:in `<main>'

    May I call the NoMethodError as dumb as my original programming-error?

    Sure, there are reasons, and how could the interpreter ever “guess”,
    what is really happening. However, this situation costs a lot of time to resolve. Maybe it is like this: “The dumber the error the dumber the message”. Shall I wait for
    “WhateverError: You sure, that programming is right for you?”

    Happy new year.
