Hi Mario, Thanks for your efforts at explaining. Yes, I'm coming to a new appreciation. With TW, you can't treat declarations and invocations as a matter of personal style. You need to understand exactly how the substitutions will take place.
So instead of: "death by whitespace?" it's simply: "Dude. Whitespace matters." :-) And it's very much worth learning, because of the results (and power) it can give you. Thanks, Mario. -- Best regards, Daniel On Fri, Feb 24, 2017 at 12:25 AM, PMario <[email protected]> wrote: > On Friday, February 24, 2017 at 7:34:03 AM UTC+1, Daniel Cunningham wrote: >> >> Finally. some observations and questions for you veterans (keeping in >> mind that I'm not at all familiar with the code base yet): >> >> - It kind of "bothered" me that the declaration "looks" like it has a >> "default parameterization", but does not really.
