Pierre,
My comment is possibly the most achieved garbage ever written, never
forget to remove the modem cable before smoking the carpet, however...
It was not pretending that you have written a bad EL optimization, just
that you didn't even consider that "optimization" could be qualified
"complication" when looked at with non Omega glasses.
Say, if VB (or even a TA language like FlexSoft TAS) can already formulate
your very elementary sample more directly in the simplest and most efficient
manner, how is your illustration supposed to be supportive of the completely
arbitrary stance that : "VB will not be more suitable because it has more
power,
and EL is already complex for the trader".
The only demonstration you provided is that EL is a questionable trader
programming language.
The rest has no substance. It's a one line technical magazine article
containing : " The editor's choice is EL ! VB is too powerful then to complex.
Period.". Very valuable, thanks.
All in all, it was possibly the worst idea to even pay attention to one more
magistral prof stance... with no proof
