Any reason not to allow default values like Classes do?

      testFoo rArg
 ;one;two
 ;three
 ;default      ← 0
 ;notDefault   ← 1

⎕← 'output'

Does the monadic ; work like ⎕shadow?

Can you pare down the example:
. remove rarg,
. pass output as a result,

There is no primitive called monadic ;. It is just that functions can "continue" the header line [0] on subsequent lines before any actual code.

This means that all locals, even those declared after line [0] are localised upon entry into the function, unlike ⎕SHADOW which dynamically localises when executed, adding an additional stack frame to do so.
