Re: Better Way to Combine Two Arrays

Parentheses are your friends.

@nums = ( (map q|1234560| . $_, 1..9  ),
          (map q|1321343| . $_, 10..99) );

That's how I'd write it too... However, I'd like to point out that `map` actually is a function, so you can use parentheses in the way tha is common for any other function: `@nums = ( map(q\|1234560\| . $_, 1..9 ), map(q\|1321343\| . $_, 10..99) );` [download]	[reply] [d/l]

But I'm not fond of the `map EXPR` syntax. A block of executable code should look like a block of executable code, and be different from the always-evaluated input list. Or so it seems to me. Unfortunately I recently found out that `map BLOCK` is actually a bit slower than `map EXPR`. I might fix that one of these days. -- Chip Salzenberg, Free-Floating Agent of Chaos	[reply] [d/l] [select]

Unfortunately I recently found out that map BLOCK is actually a bit slower than map EXPR. Entering and exiting an extra scope? Perhaps you could optimize it by skipping the scoping steps in case there are no lexical variables declared in it.	[reply]
