I don't imagine parsing the :param
comamnd presents any major challenges, especially as, :param x => ...
isn't part of the Cypher grammar.
The challenge is how that would interplay with tools that use the parameter parsing, like https://neo4j-client.net/.

Actually, one big issue would be determining what tokens are expressions and what are not. The command parsing just recognizes :<symbolic_name>
followed by arguments. Which of those arguments are to be considered Cypher expressions is entirely dependent on what the command represents, which isn't something the parser knows (because there is no standard). E.g. there is no standard that says ":param" is followed by a string, a =>
, and then an expression.
