Re: GREP case insensitivity

If you are using the grep function simply to grab the items in a list that match a particular pattern, you don't even need the curlies:

my @bintext2 = grep /$input/i, @bintext;
[download]

(note the comma after the regex)

You only need curlies if you are using grep with a code snippet (item is selected if the code returns true) -- e.g.:

my @bintext2 = grep { /$input/i and length()>20 } @bintext;
[download]

(note: no comma after the code block)

You only need curlies if you are using grep with a code snippet The reason your example needs curlies is because the `and` operator has lower precedence than the comma operator. If you use the `&&` operator then a comma works. `my @bintext2 = grep /$input/i && length > 20, @bintext;` [download]	[reply] [d/l] [select]
