Re: Improvements to gnuapl

[Christian Robert]

NARS2000-64 has already this kind of syntax while exactly having the core of 
gnuapl/apl2 for maybe 10 years.

if you want to experiment download it (windows only and free)

in feb 2015 i asked:

that said, my real question is:

how hard is it to implement the standard/or-not-as-standard-as-it-seems

:if {boolean}
  do this
:else
  do that
:endif

:repeat
  do this
:until {boolean}

:for {var} :in {list}
  do this
:endfor

:forlcl {var} :in {list}
  do this
:endforlcl

I think there is a :while :endwhile  too


thoses are really missing (to my point of view).
