# Suppose a function has an argument "x". If a "child function" has multiple
# argument beginning with "x" and I want to pass the param "x" to its parent,
# I get error: `argument n matches multiple formal arguments`
# The reason this happens is clear, but at 3am my brain is firing blanks
# trying to find a solution.  Help!
