I don't have problem with the .=, but with the while without bloc.
Is it used instead of an if ?

variables which are global but should in my opinion be declared with my
and not within a function (in pass1):
@lines
@lines2
@toc_lines
....

variables which are global but should be lexically scoped, examples in pass1
$node
$in_table
$in_pre
$html_element
.....
