#line 1 "strict.pm"

In an earlier par version it was

#line 1 "C:/perl/5.10.1/lib/strict.pm"
package strict;
[download]

So yeah, those #line number "file" directives have gotten out of sync with reality and evolved into uselessness, as have the values in %INC  strict.pm => /loader/HASH(0xaa240c)/strict.pm

This decision isn't explained anywhere

I don't see any reason for those values not to be absolute paths, esp the %INC values
