svg% ri String#split
----------------------------------------------------------- String#split
     str.split(pattern=$;, [limit])   => anArray
------------------------------------------------------------------------
[...]
     If the _limit_ parameter is omitted, trailing null fields are
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^n     supressed. If _limit_ is a positive number, at most that number of
     ^^^^^^^^^
     fields will be returned (if _limit_ is +1+, the entire string is
     returned as the only entry in an array). If negative, there is no
     limit to the number of fields returned, and trailing null fields
     are not supressed.

svg%

 you have only null fields in the result
