I have a script that optionally allows the split pattern to be specified on the command line. The default pattern is: 
my $split_pattern = ' ';

[download]

However, this doesn't DWIM with the default: 

my @x = split $split_pattern, $line;

[download]

Is there a nifty-keen way of getting the default ' ' behavior from a $variable pattern? Or am I stuck with something like this: 

my $split_pattern;
...
my @x = defined($split_pattern)
        ? split $split_pattern, $line
        : split ' ', $line;

[download]

or even 

my @x = split defined($split_pattern)?$split_pattern:' ', $line;

[download]

I'm on 5.10.1.
