I don't have a specific example to give you, but what I remember of the language
is that you must explicitely code processing price series data and specifically
code looking at previous days data. As such, in one language you have the
built in syntatic sugar to say
value1 = close - close[1];
vs
value1 = priceseries(0) - priceseries(-1);
The first is a higher-level language syntatically because it hides some of
the grittier(?) aspects of dealing with the data than the second.
I prefer the second for many reasons, but there are aspects of the first
that are more 'elegant'. The problem I most commonly have with the first
is that the langauge (EL) tries to 'help' me too much. I want more explicit
control of the language and what it is doing/calculating (as in the second)
than daily coding around the 'help' given by the first (EL).
Since EL is 'helping' so much in the processing of data a translator is
more difficult to write, but not impossible. The translator must hide
through macros or other means the implicit price series generation that
happens within EL code.
