Re^2: blocks and using braces around filehandles with print

(Not my question, but thought I'd jump in:)

So the rules here are the same as whether or not you need curlies for dereferencing an array (etc.)? e.g. @$arrayref but @{ $arrayrefs[0] } ?

I'm a peripheral visionary... I can see into the future, but just way off to the side.

There really isn't any connection between those two kinds of curlies. Those of which you speak act like parens to modify precedence and are solely used in dereferencing. `$$array[0] # Short for ${ $array }[0] ${ $array }[0] # The first element of the array referenced by $array ${ $array[0] } # The scalar referenced by the first element of @array` [download] A third, similar type of curlies is used in interpolation to show where the variable name ends. `"foo$varbar" # Equivalent to "foo" . $varbar "foo${var}bar" # Equivalent to "foo" . $var . "bar"` [download]	[reply] [d/l] [select]

Ah, okay. Thank you :) Sorry for the slight hijack! I'm a peripheral visionary... I can see into the future, but just way off to the side.	[reply]
