Keys with hyphens support

[ghpu]

Bug Report

Kubernetes uses hyphens in some of their property names. For instance "ephemeral-storage" limits.

But KCL grammar states that NAME cannot contain hyphens :
NAME: /$?[a-zA-Z_]\w*/

4. What is your KCL components version?

@ghpu Hi there. Thank you for your feedback. We can use string expressions. For example:

requests = {
    cpu = "1"
    memory = "1Gi"
    "ephemeral-storage" = "1Gi"
}

The output YAML is

requests:
  cpu: '1'
  memory: 1Gi
  ephemeral-storage: 1Gi

Thanks a lot, I was trying to use it as a compact form like requests."ephemeral-storage" = "1Gi" . But complete form suits me very well .
