I dont think this works in python. Is’nt apply() present specifically to address this?

class Hello
def __init__(self,a,b):
pass

lst = [1,2]
Hello(lst)# Error
h = apply(Hello,lst)

A dangerous and silly “feature”. I predict that this feature will have two primary end results in Groovy code:

1) Most people will be completely unaware of it and will be baffled when they encounter it out in the wild (WTF is this?!?!?). Groovy’s abysmal documentation guarantees this.

2) It will preduce really bizarre errors and behaviors where people are trying to do list things and Groovy is auto-coercing their lists into new objects. Oy!

Yet another “feature” that hasn’t been thought out and will cause more grief than good. Go Groovy!

Chris,

You are right of course, but it all gets auto converted around:

sub foo {
my %h = @_;

print $h{’a'};
}

foo(a => ‘b’);

FWIW, the ‘a => “hi”, b => 32′ perl construction isn’t a hash, you’re just using ‘=>’ (a.k.a, the ‘fat comma’) as a shortcut so you don’t have to quote ‘a’ and ‘b’. What perl sees with that is: ‘”a”, “hi”, “b”, 32′.
