Objects.
The documentation is much more extensive and perldoc
along with pod is introduced.
Lexical scoping available via my.
eval can see the current lexical variables.
The preferred package delimiter is now ::
rather than '.
New functions include:
abs(), chr(), uc(),
ucfirst(), lc(), lcfirst(),
chomp(), glob()
There is now an English module that provides
human readable translations for cryptic variable names.
Several previously added features have been subsumed under
the new keywords use and no.
Pattern matches may now be followed by an m or
s modifier to explicitly request multiline
or singleline semantics. An s modifier makes
. match newline.
@ now always interpolates an array in
double-quotish strings. Some programs may now need to use backslash
to protect any @ that shouldn't interpolate.
It is no longer syntactically legal to use whitespace as the name
of a variable, or as a delimiter for any kind of quote construct.
The -w switch is much more informative.
=> is now a synonym for comma. This is useful as
documentation for arguments that come in pairs, such as
initializers for associative arrays, or named arguments to
a subroutine.
