Re: what would you like to see in perl5.12?

in reply to what would you like to see in perl5.12?

The nested modifier, while it may have already been rejected, could have some tidy little uses.
s/foo/bar/ for (@these) if ($this);
I suppose that could be accomplished as
map { s/foo/bar/ } @these if ($this);
but is that as clear as the first statement? Using map in void context to get the effect of a for seems clumsy.

As for something I'd really like to see, interpolation of method calls in a string.

print "The 'bar' attribute of object 'foo' is $foo->bar();\n";
As it is, I get to do the oh-so-readable
print "The 'bar' attribute of object 'foo' is @{[ $foo->bar() ]};\n";
That doesn't look like it should work, but it does.

While I'm on the concept of OOP, I think I'd like to see Perl actually implement some form of strong encapsulation for objects "out of the box" as opposed to having to roll your own or re-use your "tried and true" method, whatever that may be (CPAN or home-grown).

Certainly the "defined or" (dor) functionality would be a serious benefit to prevent warnings in my code.

That's about all I can think of at this late hour. Time to sleep.
