Hi,

I haveĀ  a memory usage/garbage collection question. When you overwrite a piddle 
with a (smaller) part of itself, what happens to the original piddle? Is it 
still in memory? i.e. what happens in each of the following cases?

perldl> $a = sequence(10)
perldl> $a = $a(0:4)

perldl> $b = sequence(10)
perldl> $b = $b(0:4)->copy

perldl> $c = sequence(10)

perldl> $c = $c(0:4)->sever

Or is there a better way of dropping unwanted parts of a piddle?

Thanks,
Trevor.
