Except if the alternative to 'false' would be a scalar, you normally  
wouldn't assign it to an array, would you?

I.e., I wouldn't expect this strict of a behavior from an open-source  
package written largely from people whose job is biological science,  
not programming perl knowing and following DC to the letter ... I'd  
rather be on the safe side and assign to a scalar.

Just my $0.02 ...
