Multiple toclose on the same value..

[Francisco Olarte <folarte@...>]

One question regarding to close, just seeking confirmation ( or
denegation in case I've read the manual wrong ).

<toclose> depends on the variable going out of scope, so if I do
something like this ( I know example is stupid but something similar
may happen in more complex ways ):

do
  local original = generate_value_with_toclose_metatmethod()
  ...
  local <toclose> copy1 = original
  ...
  local <toclose> copy2 = original
  ...
end --

Will __toclose be called twice on the valuewhen reaching end ? ( I
expect it to be )

Same question with
do
   local <toclose> o = gvwtcmm()
   ...
   do
      local <toclose> c1 = o
      ...
   end
   ...
end

Will __toclose be called on reaching each end?

( 1st case is weird, but some code generation / value shuffling /
aliasing may lead to something like that, 2nd one may be more common
when reusing code via functions ( i.e., a function which does
something on an open connection closing it at end, a second function
which reads and acts upon some headers and dispatchs to the 1st one )
)

( How many times is called is not a problem to me, AAMOF I normally
dessign my "closeable" classes with an idempotent close() method, and
my plan to use <toclose> is just to alias it as __toclose, I just want
to know if I've interpreted the work manual correctly )
