Feature request: Syntax highlighting inside SugarCube backquotes

[spikymoth]

To pass an expression to a macro, you can either:

• Pass it via a temporary variable, or
• Wrap the expression in what SugarCube calls backquotes (`).

I'm not a huge fan of this feature since the syntax conflicts with JavaScript's template literals, but having to set a temporary variable for every invocation isn't great either.

Could you add syntax highlighting support for JavaScript expressions inside backquotes?

Note: Template literals can still be used in macros that expect an expression. For example, compare

<<set _temp = `foo ${$bar} baz`>>
<<link _temp "MyPassage">><</link>>

to

<<link `"foo " + $bar + " baz"` "MyPassage">><</link>>

so disambiguating them might be tricky. On the plus side, I don't think you can pass expressions to custom macros (widgets) except through the backquote syntax.
