expressions clarification

[Dino Edwards]

I'm trying to figure out what the difference between the following expressions are:

[qr'.\.(mdb)$'ix => 0]
[qr'.\.(uue)$'i => 0]
[qr'^\.(lha)$' => 0]

Mainly, trying to figure out when you put in "ix", "i" or nothing at all at the end of the expression.

Thanks

'x' means ignore whitespace and comments
'i' means ignore case

Is there a scenario where whitespace, comments and case should not be ignored?

i = ignore case
x = ignore (most) whitespace and permit comments in pattern
