This
course
is
for
those
who
already
have
strong
knowledge
of
Perl's
techniques
for
handling
control
structures,
data
structures
such
as
arrays
and
hashes,
text
file
processing
and
regular
expressions,
as
provided
by
the
course
'Perl
Programming
&
Applications'
('IB-103').
A
large
part
of
the
course
deals
with
Perl's
approach
to
handling
complex
data
structures,
including
implementing
object-oriented
programming
in
Perl.
The
course
extends
consideration
of
the
use
of
references
and
modules
well
beyond
that
provided
in
the
course
'Perl
Programming
and
Applications',
as
well
as
exploring
typeglobs.
These
techniques
are
then
used
to
underpin
detailed
examination
of
object-oriented
programming
in
Perl,
including
the
tie
function
and
closures.
The
last
part
of
the
course
covers
advanced
and
miscellaneous
functions,
constructs
and
issues
not
covered
in
depth
in
'Perl
Programming
&
Applications'
('IB-103').
