There is only one line to know:

Presumably a lot of people uses scripts from these lessons (that are
pretty good, recommended for beginners). So "forget pretty quickly"
seemed
not appropriate to me. And a candidate for your "certain percentage" is
each and every beginner.
I wasn't getting angry - hence the 'wink' at the end...
It was just merely a reminder that none of us are 'omnipotent' - its
always useful to reference discussions if they are mixed from different
places (there's a lot of posts everywhere, and many times we can only
survey the headlines).
But please don't judge this as 'bug'. It is a wonderful feature!
Beginners can learn from it. Would be better to explain the advantages
and
disadvantages for using spaces instead of commas (one could use parts
of
this thread).
In general I'd perhaps say that we should normalize the lessons to use
code forms which are considered best practice - so I would consider
lessons which use spaces and not commas as a bug for this reason.
I'm not sure I can see that using spaces between arguments *is* in any
way best-practice as it hides a required notion when you actually have
to call the command (and can hide subtle typing errors as Paul pointed
out) - the synergy between parameter declarations and parameter use is
probably an important concept thus should be reinforced at every
opportunity.
Something Richard mentioned about '=' being used in constant and var
init also sticks in my mind as slightly jarring - it is perhaps
something we should tweak to allow 'is' and '=' (yes, *technically* a
synonym, but we can make the 'is' form strictly preferred as a slightly
better way of expressing what you mean):
constant kFoo is 100
local tVar is 200
In LCB, we chose 'is' rather than '=' for very much this reason.
I think it is probably generally true that the more consistent and
simpler the language is, the easier it is to learn.
Warmest Regards,
Mark.
