since we have 2 forms of "return" -- "return" and "leave" , may be we
can make "return" also to be a topicalizer for the rest of experssion
, and then :
return baz(@args) when $_ $_ > 0 ;
return baz(@args) when defined ;
return baz(@args) when true ;
but then inside given we will have to use "leave" :
given $x {
leave baz(@arg) when 5 # compare with $x
return bar(@arg) when 5 # compare with rezult of bar(@arg)
}
or maybe we have to have anothre name for return which also
topicalize.
