It's a perl feature.  On warn's it'll add the filehandle and the
line number when it's relevant.

5.6.1:

$ ~perl/bin/perl -e 'warn "foo"; open F, ".bashrc"; warn "Foo" while <F>' 2>&1 | head -5
foo at -e line 1.
Foo at -e line 1, <F> line 1.
Foo at -e line 1, <F> line 2.
Foo at -e line 1, <F> line 3.
Foo at -e line 1, <F> line 4.

If you set $/ so it's not reading normal lines it'll say chunk
instead of line:

$ ~perl/bin/perl -e 'warn "foo"; $/ = undef; open F, ".bashrc"; warn "Foo" while <F>' 2>&1 | head -5
foo at -e line 1.
Foo at -e line 1, <F> chunk 1.


Older perl's always said "chunk".

perl 5.5.3:

$ perl -e 'warn "foo"; open F, ".bashrc"; warn "Foo" while <F>' 2>&1 | head -5
foo at -e line 1.
Foo at -e line 1, <F> chunk 1.
Foo at -e line 1, <F> chunk 2.
Foo at -e line 1, <F> chunk 3.
Foo at -e line 1, <F> chunk 4.
