Hello jmmitc06,

The syntax:

@smrow = @{$sm_rows[$_]};

[download]

doesn’t just perform a dereference, it also copies the contents of the right-hand side into @smrow. So you have to balance the additional overhead of making copies against the saving on dereferences within the loop.

Update: Perhaps you should investigate the Data::Alias module on . For example, you can replace @smrow = @{$sm_rows[$_]}; with:

use Data::Alias;
...
alias @smrow = @{$sm_rows[$_]};

[download]

which avoids any copying of the data.

Hope that helps,
