I doubt anyone's arguing that they're not function calls. What I find
"surprising" is that Perl doesn't DWIM here. It doesn't encourage data
encapsulation or try to make it easy:
my $weather = new Schwern::Example;
print "Today's weather will be $weather-{temp} degrees and sunny.";
my $weather = new Schwern::Example;
print "Today's weather will be $weather-{temp} degrees and sunny.";
print "And tomorrow we'll be expecting ", $weather-forecast;
You are wicked and wrong to have broken inside and peeked at the
implementation and then relied

Oh joy: now Perl has nested quotes. I *hate* nested quotes.
Those are single-quotes inside double-quotes.
Yep: nested, with varying semantic effects. Completely nasty.

As Nate pointed out: print "$hash-{'f'.'oo'}" already works fine and
the world spins on.
That is no argument for promoting illegibility.

Method calls should interpolate in double-quoted strings, and similar
locations.
print "Today's weather will be $weather-temp degrees and sunny.";
Would deparse to:
print 'Today\'s weather will be '.$weather-temp().' degrees and sunny.';
So, the - operator is supposed to get expanded

So, the - operator is supposed to get expanded in dq strings, eh?
It already does, or at least appears to to users:
print "Today's weather will be $weather-{temp} degrees and sunny.";
Sorry, I wasn't subscribed to perl6-language-objects and didn't even
realize there was a discussion going on. I just fixed that.
I didn't mean to hijack RFC 103, I can't remember if I'd even looked
at it before... but Nathan seems okay with that and it is a
deceptively large issue.

We're not talking about stands of pine trees, presumably.
Funny, I know how to type extended characters in MacOS, but I have no
idea how to do it in X. Hell,
The only decision, then, is to decide which context to use; if it deparses
to concatenation then it seems logical to use scalar context. This also
makes sense in that you can force list context with @{[ $weather-temp ]} if
you really wanted it.

This topic is actually covered, albeit far less in-depth and lumped with an
unrelated change, by Nathan Wiger's RFC 103, just in case you weren't aware.

Yeah, I've got to split those up. I was trying cut down on the flood of
RFC's that poor Larry has to sift through :-(, but they are both

This does not DWIM. Instead of interpolating C$weather-temp as a method
call, it comes out as C$weather.'-temp' and is usually followed immediately
by the question "What does

However if temp() calls wantarray(), the result will be FALSE (scalar).
I think what he's trying to get at is that these
16 matches
