[Bug-apl] No errro message when defining functions using

[Elias Mårtenson]

When I try to define a function that takes no arguments, but does include
an axis argument, the normal function editor complains:

      *∇foo[x]*
bad editor command '∇foo[x]' : problem 'Bad function header at Nabla.cc:495'
DEFN ERROR
      ∇foo[x]
            ^


However, if I try to define the same function using ⎕FX, it gets defined:

      *⎕FX 'foo[x]' 'x'*
1
      *)fns*
EMACS_NATIVE    bar     foo


But, it cannot be called:

      *foo[1]*
1
SYNTAX ERROR
      foo[1]
      ^  ^
