If so, some consideration should be made as to which syntax is preferred
to solve this problem generally for both setting properties and calling
methods.
I prefer the "obj { .. }" syntax because it mirrors object literals in
JSON/JavaScript, object initializers in C# and C/C++ and Haskell record
syntax, is particularly concise when nested to create large trees of
objects, and avoids the noise of "->>" on each line.
All the examples you've given for that syntax are for initialisation,
and I'm not sure how readable it would be for the general "do several
things in a row" case:
$counter {
count(),
count(),
count(),
count()
}
Thinking about it, this becomes something more like a "with" keyword:
with ( $counter ) {
count();
count();
count();
count();
}
If with(){} could be used as an expression, you'd get something
remarkably close to your initialiser example:
$this->setBlah(
with ( Blah::create(4) ) {
foo = $foo;
baz = with ( new Baz() ) {
markFixed();
label = "Hello";
};
setBot(9);
}
);
I'm not sure if this is a good thing or not - with() statements exist in
a few languages, with varying degrees of acceptance. I don't remember
seeing one used as an expression like that before, though.
There's a definite awkwardness of what to put on the left side of
property assignments too...
with ( new Foo ) { var = 1 }
with ( new Foo ) { $var = 1 }
with ( new Foo ) { ->var = 1 }
Overall, it's an interesting idea, but the details are fiddly, and the
gains marginal, IMO.
