@nfrankel: Couldn’t this be achieved with some extension functions? I don’t think there is any need to modify the API.

@arthur: extension functions add properties/behavior in that case, we want to change the existing behavior this calls for a new type

@nfrankel: why can’t add(element), remove(element), put(key, value) be implemented with extension functions. It would just require a new immutable collection to be created with the elements copied plus or minus the element you are adding or removing

@arthur well, it's not just simple addition or removal, it's a special implementation as has been mentioned in the proposal, currently based on http://pcollections.org/

as for extension functions, Kotlin already has stuff like this over the standard Java implementation of collections

Building and testing a parser with ANTLR and Kotlin by Federico Tomassetti http://tomassetti.me/building-and-testing-a-parser-with-antlr-and-kotlin/

I wouldn’t put

multiLineString

into

ParseTreeElement

, I’d rather make it extension function and do

when

-dispatch on AST node types. And then put it into test module, because it’s actually more like

makeTestString

.
