If that's all you do, then the easiest approach is to write both the
function and the macro.
Assume you have the function version, called to-keyword* ("foo*" is a
naming convention for something that is a "variant of foo"), then the
macro is as easy as:
(defmacro to-keyword [sym]
`(to-keyword* ~sym))
the driver function idiom is very common and useful, as writing
functions is much less error prone than writing macros. This approach
also has the advantage that if you ever need to transform a collection
of symbols, all you need to do is map the to-keyword* function.
