Re: Strange behaviour with Arrays and print?

Actually, I'd say it's pretty strange indeed

perl -E 'my @a=qw(10 20 30); say "@a!"; say @a . "!"'
[download]

Output:

10 20 30!
3!

I always thought that things like "$foo\n" were compile-time shortcuts for $foo . "\n". Apparently not, at least not for arrays...

But in the spirit of your example code, the compiler might proceed something like: `Source "@a\n"` `Becomes "@a" . "\n"` `Becomes join($", @a) . "\n"` `Becomes "10 20 30" . "\n"` `Becomes "10 20 30\n"` with `join($", @a)` (or its runtime equivalent) still providing list context to the array.	[reply] [d/l] [select]

You're right, of course. Also, it appears that Perl has different overloads for for string concatenation and stringification. Interesting... I never knew that.	[reply]
