Description

Information:

  • Prism version: 1.29
  • Plugins: none
  • Environment: Browser

Description

With this code:

(let ()
  `(let ()
     (display "x")))

The second let inside the backquote is marked as a name, not a keyword. It's important for writing macros and looks odd that the second let is white (in Coy) and not blue.

Research direction

Reproduce the Scheme snippet in Prism's browser environment and inspect the Scheme syntax-highlighting grammar responsible for classifying identifiers inside backquoted expressions. Update the classification so the nested let is highlighted as a keyword, then verify that the example renders consistently with the expected keyword styling.
