- Added support for class attributes
In addition to class paraterms, which are also instance class attributes, a new way of declaring attributes has been added, using the `has (attr1, attr2, ...)` syntax.
Example:
class Foo {
has value = 42
}
var a = Foo()
var b = Foo()
a.value = 99 # changes value of `a` to 99
say a.value; # prints: 99
say b.value; # prints: 42
- Minor fixed for Array.first(n) when array has less than n elements.
Example:
var arr = [1,2,3];
say arr.first(10); # returns: [1,2,3]- Loading branch information
