lib Update Request

I'm Writing a ThemeColor Plugin, use Visitor.

In fn:visitColor , node.parent sometimes is null (box-shadow:0 0 0 1px #999 inset). I can't find the parent Declaration Node of Color Node.
so I want to [less.js/lib/less/visitors/visitor.js Visitor.prototype.visit](https://github.com/less/less.js/blob/0e268598c8327b9e8d36d9bb2edfde95d8d787be/packages/less/src/less/visitors/visitor.js

I expected ? to not overwrite the query, but to merge. The docs of the proc use the word "concatenate" which implies that this is how the proc should work, but the implementation overwrites the query instead of concatenating.

Example

import uri
let foo = parseUri("https://google.com/?page=10")
echo(foo ? {"test": "42"})

Current Output

https://google.com/?t

It would be nice if using the built-in debug function in .60 files autogenerated Rust code which used the debug macro from the log crate. This would allow applications to choose the logging implementation instead of always printing directly to standard out. It would also be nice to add functions for the other log levels (trace, info, warn, error).
