OK, a method is something you call on an object, using a the dot

current lexical scope.
If write was a sub, it would work exactly as you described:
48: my $Handle = open( $DateFile, :rw )
53: write( $Handle, $OldDateTime );
And if you wanted to, you could even refer to it by name...
my $func = &write;
$func( $Handle, $DateThing );
But it's not a sub, so it needs to be invoked on the object:
53: $Handle.write($OldDateTime );
- or -
67: $Handle.write: $DateTime;
Hi Brent,
Now I am confused.
I thought that when you wrote
$x.AA.BB.CC
What you were doing was passing the result of AA($x)
to BB and its result to CC
Sort of like
CC( BB( AA ($x) ) )
Only a heck of a lot easier to read,
Now I am not so sure.
When you say
$Handle.write( $OldDateTime );
"write" is an object" not a sub. By chance does this
apply to both objects AND subs?
And does
$Handle.write: $DateTime;
also apply to subs?
