I have update branch. Do some fix and create testcase.
Now you can run
/perl/lib $ PERL5DB='BEGIN{ require "./perl5db.pl" }' perl -Iperl5db/t -d
perl5db/t/apply_users_pragma_when_eval
ACTUAL RESULTS:
Loading DB routines from perl5db.pl version 1.49_03
Editor support available.
Enter h or 'h h' for help, or 'man perldebug' for more help.
main::(perl5db/t/apply_users_pragma_when_eval:5):
5: my $l = MyMaths->new(1.2);
DB<1> n
main::(perl5db/t/apply_users_pragma_when_eval:6):
6: my $r = MyMaths->new(3.4);
DB<1> n
main::(perl5db/t/apply_users_pragma_when_eval:7):
7: print "A: ", $l + $r, "\n";
DB<1> n
A: 4.6
main::(perl5db/t/apply_users_pragma_when_eval:9):
9: print "B: ", $l + $r, "\n";
10: {
DB<1> n
B: 4 <<<<<<<<<<< NOTICE HERE
main::(perl5db/t/apply_users_pragma_when_eval:11):
11: no myint;
DB<1> print "B: ", $l + $r, "\n";
B: 4.6
BUT EXPECTED:
B: 4
http://perldoc.perl.org/perlpragma.html
A: 4.6
B: 4
C: 4.6
D: 4
E: 4.6
