How to index into array from a function

[Despite]

Is there a clean way to index into an array returned by a function?  When I try to do it directly, I get a parser error.  I have to assign the array to a new variable and index that.

# This fails
$dc = split($domain,'[.]')[0]

# This works
$split_domain = split($domain,'[.]')
$dc = $split_domain[0]

I guess it really doesn't matter, it's just annoying and breaks my expectations.

I've seen another area recently where the return values of functions cannot be used directly as an ordinary value (they cannot be used as resource titles).  I suspect that the parser just doesn't anticipate those cases, but perhaps there's something about the grammar or implementation that makes such cases hard.  I encourage you to file a feature request.
