Hi Risto and all:
I have been looking at the 2.7 alpha release and I have a few
comments. The functions that deal with setting a variables from some
context seem to have different calling conventions
copy, empty, pop, shift
all take "<name> %<var>" as arguments while:
exists, getsize, getaliases, getltime, getctime
take "%<var> <name>". Is there a reason for this discrepency? I can
see getting really confused about which goes where depending on the
function. I would suggest making all of them consistant and use
"<name> %<var>" for all the functions above.
Functions like assign, eval, call or lcall sensibly have the variable
as the first argument since the second argument is potentially
multiple words long (a string and perl code, param lists etc).
Also to make while/if more useful I think a shortcut like:
if exists(<name>) ( action_list ) else ( action_list2 )
while exists(<name>) ( action_list )
is more readable compared to:
exists <name> %B; if %B ( action_list ) else ( action_list2 )
exists <name> %B; while %B ( action_list; exists <name> %B )
In general maybe any function that sets a variable can return that
value for an if or while condition clause. So 'exists' can be replaced
by 'getsize', 'getaliases', 'pop', 'getltime' ....
