Hi all, I parsed XML into an array/hash ref 'struct' and tried to acces the data wrong, ie treating a hash ref as an array ref or vice versa. The result was that the perl process ate all memory which, of course, isn't a very nice thing.

Is there a good way to avoid thoose pitfalls, except using more simple data structures and not coding wrong?
Here's an example that consumes all my memory at least:
perl -e 'use strict; my $a = { child1 => [ {child2 => [ { child3 => [ 
+{child4 => [ 1 ] } ] } ] } ] }; print $a->{child1}{child2}{child3}{ch
+ild4}, "\n"'
