Its nearly always a bad idea to just translate code structures from
one language to another. It will usually be sub optimal and non
idiomatic - thus harder for the 'native' programmers to
understand/debug.
Bjarne Stroustrup made the same observation when C++ first came out
and lots of Smalltalkers tried to use it like Smalltalk. He said
"C++ is not Smalltalk, if you want to write Smalltalk use smalltalk"

Yes, or PHP. Both have RE baked in.

I can cope with that - BASIC does the same kind of thing - but
its the zillion ways to handle errors that bug me!
do thing until die
do thing or die
die unless do thing
etc....

A huge understatement! :-)

I don;t know but in cases like these I use parentheses like amaniac:
if ( ((not $d) eq "a") && ((not $d) eq "c") )
Or did you mean
if ( (not ($d eq "a")) && (not ($d eq "c")) )
Or was it
if ( (not $d) eq ("a" && not ($d eq "c") ) # OK thats a bit
unlikely...

Clever abbreviations apparently!
I don't even like the $ and @... one reason I can never quite feel
happy with Ruby. It has fewer of them but still more than I like.

Nope, I'm quite happy for it to be used in file indirection and
even for right/left bit-shifting. But I don;t like it being part
of the filename - I agree with that!

Good summary! Perl reflects the fact that its inventor is a
natural-language student not a computer scientist. It tries to
incorporate the "richness of expression" of natural spech.
But when dealing with machines that's a flaw IMHO!
