#9183: creating an expect element can modify a previously created expect element
--------------------------+-------------------------------------------------
Reporter: saliola | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-4.4.4
Component: interfaces | Keywords: gap
Author: | Upstream: N/A

--------------------------+-------------------------------------------------
The {{{_next_variable_name}}} method in the expect interface sometimes
spits out a variable name that is in use. This means that a previously
created element might be modified inadvertently:
{{{
sage: z = gap(3); z
3
sage: gap.clear(z.name())
sage: gap.clear(z.name())
sage: x = gap(3); x
3
sage: y = gap(4); y
4
sage: x
4
}}}
Of course, x should be 3 above, and not 4.
(This issue was found in #8380, but it didn't get resolved there. See the
ticket for more details.)
