in reply to Mastering Regular Expressions

One nice feature of the book (both editions) should also be mentioned here: Its singularly ingenious typesetting.

Using a sophisticated but quite intuitive notation the author maintains always a clear picture of what portion of an expression or position in a string he is talking about, where exactly literal space characters occur, what matches what, which parentheses belong together, and so on.

This is a significant factor in keeping the discussion of such complex matters concise and straightforward. I have yet to see other technical writing reaching the same level of clarity through just the right kind of typesetting.

[Lady_Aleena]: Hello everyone. I'm having a blonde moment. I can push an array to an array, right? push @to_array, @another_array;
[shmem]: of course
[shmem]: the members of @another_array are conflated to @array
[shmem]: try it out:
[Lady_Aleena]: shmem, thanks. I'm am way out of practice.
[shmem]: perl -lE '@foo = (0..3);@bar = (4..7); push @foo,@bar; say for @foo'
[Lady_Aleena]: shmem, I feel like an idiot for forgetting something so basic.
