Re: arrays, context, and print

print +(1,2,3,4)[3]
works, because the + tells perl that the () are a list and not enclosing the parameters for the print function. Otherwise perl would understand something like ( print( 1, 2, 3, 4 ) )[3]

print scalar (1,2,3,4)[2];
Doesn't work, because you seem to want the scalar value of an array (it's size), but you're specifying a list. That's a difference you should read up on. SuperSearch should give enough info though ;)

`print scalar (1,2,3,4)[2];` [download] Doesn't work, because you seem to want the scalar value of an array (it's size), but you're specifying a list. I think that you are wrong on this one, notice: `print scalar (1,2,3,4)[2]; # syntax error at )[ print scalar((1,2,3,4)[2] ); # prints 3 print scalar+(1,2,3,4)[2]; # also prints 3` [download] Your first answer applies to both. The `scalar` is just hogging the parens. It is also useless, as it is forcing a scalar context on a scalar.	[reply] [d/l] [select]

Thanks phaylon. I think the docu for + I wanted was in perlop: "Unary ``+'' has no effect whatsoever, even on strings. It is useful syntactically for separating a function name from a parenthesized expression that would otherwise be interpreted as the complete list of function arguments. (See examples above under Terms and List Operators (Leftward).)"	[reply]
