replace junior semicolon with actual one

replace junior semicolon with actual one

commas can be used in two ways, quoting Perl Best Practices (PBP):

> The comma actually has two distinct roles in Perl. In a scalar
> context, it is (as those former C programmers expect) a sequencing
> operator: “do this, then do that”. But in a list context, such as
> the argument list of a print, the comma is a list separator, not
> technically an operator at all.
-- PBP, page 69

And the separating variant is called a "junior semicolon" by PBP.
