'global variable XXX not found' error at nested import

[PellSmit]

In case of nested import like bellow,
LSLForge reports an error saying 'global variable A not found'.
I fixed it but need more test.
Wait for a while.

----------A.lslm ---------------
$module (integer A)
----------B.lslm ---------------
$module (integer A)

$import A.lslm(A=A);
----------C.lslm ---------------
$module (integer A)

$import B.lslm(A=A);
----------D.lslm ---------------
$module (integer A)

$import C.lslm(A=A);
