perlref - Perl references and nested data structures
Before release 5 of Perl it was difficult to represent complex data structures, because all references had to be symbolic--and even then it was difficult to refer to a variable instead of a symbol table entry. Perl now not only makes it easier to use...

perlrun - how to execute the Perl interpreter
The normal way to run a Perl program is by making it directly executable, or else by passing the name of the source file as an argument on the command line. (An interactive Perl environment is also possible--see perldebug for details on how to do tha...

bench.pl - Compare the performance of perl code snippets across multiple perls.
By default, bench.pl will run code snippets found in t/perf/benchmarks (or similar) under cachegrind, in order to calculate how many instruction reads, data writes, branches, cache misses, etc. that one execution of the snippet uses. Usually it will ...

perltrap - Perl traps for the unwary
The biggest trap of all is forgetting to "use warnings" or use the -w switch; see warnings and "-w" in perlrun. The second biggest trap is not making your entire program runnable under "use strict". The third biggest trap is not reading the list of c...
