Hi all,
this whole discussion got ridiculously complicated.
But in fact it is so simple!
A function call in PicoLisp is *always* just a single cell:
+-----+------+
| Fun | Args |
+-----+------+
Both Fun and Args can be anything (number, symbol or pair).
If Fun is a number, the expression auto-quotes. Otherwise, while it is a symbol,
its value is taken. So we end up either with a number (code pointer) or a list
(EXPR, FEXPR, or a mixture of both). This is called with Args.
Fun is free to do with Args what it wants.
Who cares about proper or improper lists? Total freedom and power! :)
'quote' is the mother of all functions. It does nothing, and just returns Args.
No need for "special forms"!
