trick/vars-as-template-placeholder
In Lisp it is not always clear when something is a symbol or a variable.
In Dok I can use $var for variables:
- the syntax show when something can change
- it is the idea of a placeholder for a value that can be substituted
Symbols instead are used for
- fun names
- class names
- package names
In CL refences can be substituted by quasi-quotation
(let ((x 4))
(equal (f x) (funcall `(f ,x)))
