why do I have to provide context to split result in a separate statement?

Mark_Galeck has asked for the wisdom of the Perl Monks concerning the following question:

Hello, why does this bomb

print @{\(@arr = split / /, '')}
[download]

while this does not

@arr = split / /, '';
print @{\@arr}
[download]

Thank you, Mark

`\(@arr = split / /, '')` returns a list of references. For example `\( $a, $b, $c )` is actually `( \$a, \$b, \$c )` and you can't dereference that as an array. What you could do is copy the list to an anonymous array: `print @{[@arr = split / /, '']}` [download]	[reply] [d/l] [select]

Don't need to copy it into two arrays. `print @{[ split / /, '' ]}` [download]	[reply] [d/l]
