From mjtg@cus.cam.ac.uk

compiles without error. But omitting the apparently redundant
second semicolon gives

% perl -w
{ package DB; use vars '$single'
}
syntax error at /home/mjtg/perl5.005_03/lib/vars.pm line 1, near "package vars"
BEGIN failed--compilation aborted at - line 2.

Happens on all versions of perl up to 5.005_62.

Presumably some lexer state is leaking between the main program and
vars.pm .

:Happens on all versions of perl up to 5.005_62.

Just for the record (mainly the bugdb), this is fixed in 5.6.0.
