Perl is at the mercy of your machine's definitions of various
operations such as type casting, atof() and sprintf().
If your stdio requires an seek or eof between reads and
writes on a particular stream, so does perl. This doesn't
apply to sysread()
While none of the built-in data types have any arbitrary
size limits (apart from memory size), there are still a few
arbitrary limits: a given identifier may not be longer than
255 characters, and no component of your PATH may be longer
than 255 if you use -S. A regular expression may not compile
to more than 32767 bytes internally.
