local $/; print "@{[ <DATA> ]}\n";
Sure, you CAN do that.
- Creates an array
- Fetches the file contents
- Puts that in the new array, as one element
- Copies the array element
- Throws the array away
- Adds \n
- Passes a large string to print
Rule of thumb: do not use the idioms explained in the root of this thread, unless you really have to interpolate (like in regexes, although (??{}) may be a better idea). Especially the array creating one.
