kotlin - Is it possible to hide variables from lambda's closure? -


i'm trying crate type-safe groovy-style builder in kotlin it's described here. problem visibility of lambda receivers in nested lambdas. here simple example.

html {     head(id = "head1")     body() {         head(id = "head2")     } }

receiver of nested lambda body doesn't have 'head' method. nevertheless code compiles , prints this:

<html>     <head id="head1"></head>     <head id="head2"></head>     <body></body> </html>

it expected there way compilation error on inner head?

as of kotlin 1.0 not possible. there open feature request functionality.
