closure & local_variables

Marcin Mielzynski

Hello,

given:

l=lambda{p local_variables;p a}
a=:whatever
l[]

I know that 'a' variable shoud not be visible for closure, but why
local_variables reports that it exists ? Is this behaviour intended ?

l is closing over main, main has a local_variables method, that is
what is being called not the proc's local_variables.

Well, #local_variables is a method call so it resolves
at call time (at which point a is included). You could
also #eval 'a' at that point :)

Is the CSV file linked from a URL on a page, or the result of a form
submission ?

If a link (or form submission using GET) then you could probably download it
directly using xmlHttp.
