If it doesn't follow a well recorded, defined list of types, it isn't
"Hungarian".  On one hand, I've often found it useful to distinguish
between parameters ($p_) and local vairables ($l_) in my functions and
methods, on the other hand, it kind of defeats the purpose of
auto-complete, since all your variable names begin with a small set of
notations. On some occasions I've even found it useful to go so far as
to add notation for keys ($k_) and values ($v_) in my longer loops,
but that is definitelly not "Hungarian". I can't really ever recall a
time where the type hinting character ever helped me out, but maybe
someday... That being said, type and scope hinting in a name can be
useful, and as far as I'm concerned are as much an indication of what
a thing is as some arbitrary label, in fact, it can often make your
names shorter and more to the point. For example compare taking an
input array of $p_aNames, looping through them as $v_sName and
building some local array for return in $l_aNames against using
longer, studlyier names for the "Name" to differentiate them, such as
$NamesInput, $NameFromLoop, $NamesOutput. Typically, on a project, I
wait until it is late and I've had a few beers to start naming things
anyway, so anyone following my example is probably in deep trouble.
