Comment (by nbruin):
The current branch solves the problem by augmenting the "variable clear"
function with an "unintern" of the corresponding lisp symbol. It seems to
work OK, but I'm not 100% sure whether it's safe to do so. If one ends up
deleting a symbol that is used elsewhere in expressions, then uninterning
the symbol could lead to very funny situations: the next time the symbol
gets created from a string, a new (interned) symbol would be created,
leading to two distinct symbols with identical print names.
{{{
from sage.libs.ecl import ecl_eval
def ecl_symbols():
return set(ecl_eval("""(let ((lst ())) (do-all-symbols (s lst) (push s
lst)) lst)"""))
A = ecl_symbols()
while True:
_= sin(x).simplify()
B = ecl_symbols()
print B.difference(A)
A= B
}}}
