Hi.

>Note that splitting an EXPR that evaluates to the empty string always produces zero fields, regardless of the LIMIT specified.

Please clarify what 'zero fields' mean. Is this empty string or undefined value?

print map{ defined? "YES" :"NO"} split('b', "bd"); # YESYES

print map{ defined? "YES" :"NO"} split('b', "b"); # NOTHING IS PRINTED

print map{ defined? "YES" :"NO"} split('b', ""); # NOTHING IS PRINTED


would it be better to say:

>Note that splitting an EXPR that evaluates to the empty string does not produce fields at all, regardless of the LIMIT specified.
