e.g.
You can take the following 'C' program as an example. Write the same in
perl and enjoy the gunk that comes out.
int
main(int argc, char **argv, char **envp)
{
__write(1, "hello world\n", 12);
}
The equivalent program in perl would be
#!/usr/bin/perl
print "hello world\n";
(just two lines instead of 5 lines in the 'C' program. But an strace on both
show
the C programs does the same job with 23 system calls
the perl program takes 160 system calls to just print the line "hello world"
on screen
Come dude ! ...that's a lousy argument and you know it. I, myself, prefer
python
to C and C to perl ...but won't ever look at number of syscalls to defend my
preference.
If you *really* want to go that way and do a 'relevant' one-to-one comparison,
you have to include the number of syscalls being made by gcc when compiling
your
code to binary ...which is essentially what the perl interpreter is doing for
you for 'free'.
