Are compiled maxima functions lexically scoped????



Sigh....

I thought interpreted and compiled maxima functions were supposed
to behave identically but now I see they do not even on very simple
examples.

My very rudimentary testing shows that my favorite examples

f(s,t):=s[t]

and

f(s):=s[1]

seem to behave as expected when compiled whereas they behave strangely
when interpreted (see 
http://maxima.sourceforge.net/wiki/index.php/LexicalLayer).
