So where do we go from here?
a. <function name>.<arg name>
b. <this>.<arg name>
c. ':'<argname>
d. just <argname>
option a,b and d are easy to implement.
option d would be least clear and readable considering
sql functions can be long and have multiple arguments.
option c is more difficult because gram.y has to be modified
to understand ':'<identifier> as parameter but not a target_list item.
option a and b would make the source more readable
but extra documentation has to be provided to describe
how to refer arguments by name.

Gevik
