Well, after re-reading the text in Learning Perl, it does in fact say that you can
replace ANY comma
with =>. I find this quite interesting, so I did a quick test:
@A=('Big City'=>'Little City'=>'New York'=>'Mayberry');
print @A;
produced:
Big CityLittle CityNew YorkMayberry
So, I do another test:
I did a search and replace on a currently working program, replacing all commas
with =>'s.
The script still works from the command line and browser, but crawls via the browser (
a quick
estimate of 60 times slower). The only change was the comma replacements.
So, once again, Randal (and Tom) is correct and I learned something new. I can't
see that this
would be a good way to declare your arrays (or most anything for that matter unless
you are in an
obfuscated contest). My question is, since the left hand side is implicitly quoted,
could this
cause any problems?
