• (get-source x)
Returns a string of the source code for the given symbol, if it can
find it. This requires that the symbol resolve to a Var defined in
a namespace for which the .clj is in the classpath. Returns nil if
it can't find the source. For most REPL usage, 'source' is more
convenient.

Example: (get-source 'filter)
