Here's another example from gtk-simple:
https://github.com/perl6/gtk-simple/blob/d1fcc6efe1da3fd88a26b4328d6537c58607dee7/examples/07-text.pl6

whoops, that should be
with GTK::Simple::Button.new(label => 'bcd') {
.clicked.tap({ .sensitive = False; $button.sensitive =
True; });
}
alas I am on win
That's a nice & small answer. It does seem overkill for the gtk example...
use v6;
use GTK::Simple;
with GTK::Simple::App.new(title => 'abc') {
my $app = $_;
my $button;
.set-content:
GTK::Simple::VBox.new(
GTK::Simple::Button.new(label => 'bcd').clicked.tap({
Looks like I can get pretty close to what I was looking for with this
subroutine:
sub cascade ($obj, &proc) { proc($obj); $obj; }
Then, given the Point class again:
class Point { has $.x is rw; has $.y is rw; }
this:
(Point.new.&cascade: {.x = 10;}; Point.new.&cascade: {.y = 20;})

Ah yes, and that's a great feature. I forgot that "with" skips over
the block when the topic is undefined, and that is very useful.

Hmm- what's the benefit of with's defined check? Seems like it makes
"with" break if used with type objects

For your particular case, would it be sufficient to set the values in
the constructor?

Normally, that would be a good way to construct the Points in my example.

Hello,
Here's a simple class:
class Point { has $.x is rw; has $.y is rw; }
'with' seems to return the result of evaluating the block. E.g. this
expression will return a Point:
with Point.new { .x = 10; $_; }
Whereas this will return 10:
with Point.new { .x = 10; }
Is there a way
