‘as’ is different from a Java cast currently in that ‘as’ forces a smart coercion. Casting remains the same as Java (in that it could barf and doesn’t do anything clever).

It’s not that I’m offended… But you managed to make typos on both my first and last name. Now… I’m used to people making typos with my last name. But both at the same time… You’re the king ;-)

Of course this is all a red herring – “as” isn’t proposed here to fix the array problem per se. The real reason for “as” is because some Groovy people thought it’d be neat to get rid of Java style casts and invent a new cast syntax. That’s what “as” here, and the Groovy guys are merely trying to apply “as” to the arrayList problem.

I think that either strong typing or casting could be used so I could say :

int[] x= [1, 2, 3]
x= (int[]) [1, 2, 3]
x= (TreeMap) ["name" : name, "value" : value]

The first two case should work a bit like autoboxing. The third case would be like creating a new instance of the TreeMap class and then adding the entries.

works great too…. for the Array case.

I like the ‘as’ for chosing types of lists and maps.

“I want a list, oh and use this type for me will you?”

“I want a list, oh and use an arry will you?”
