lib Update Request

I think the Carbon project would welcome a proposal to add an explicit syntax that forces a tail call. This is aligned with our goals of predictable performance and giving the user explicit control.

My syntax suggestion: tail return F(...);.

Background:

• [[[clang::musttail]] attribute for guaranteed tail calls.](https://reviews.llvm.org/D9951

Whiskers' regex looks for <..> as opposed to tokenizing the input, so it is not able to detect truncated/mistyped input.

For example it can't detect that <!b is not terminated in<?b> X <!b Y </b>.

With some heuristics it could be improved: match for <?, <! and </ and only allow identifiers which are terminated with >, otherwise it is invalid.

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.

Example run

Having a callback for when the selected element is changed would be useful, for similar reasons to TextEdit/LineEdit: validation, updating buffers, or the rest. I imagine that it would be something like selected(int) with int being the index, though LineEdit emits a simple callback without arguments so there may be a tradeoff I'm missing (an int should be easier to pass around on the oth
