Per a suggestion by Christian Robert, edif and edif2 now support creating and editing
named lambdas. (Though, to be honest, the usual way of creating a named lambda,
fubar←{whatever}, is easier--I just included the "create" capability for
completeness. The only real value of lambda mode is editing existing lambdas.)
Note:
My suggestion was initially to refuse to "edif" named "Lambda" function, mainly
because they cannot be saved back to the workspace at all using regular function editing in edif.
Chris Moller made it possible after my initial request. I'm really glad he made
this possible.
thanks,

Lambda-editing mode differs from normal function-editing mode in that no header
is shown in lambda mode (APL creates the header based on the alpha (⍺) and
omega (⍵) variables in the expression). Lambdas also have an implicit λ←
assignment; that assignment is not shown in the editor.
So, for example, if you create a lambda like
fubar←{3×⍳⍵}
and then edit it with edif:
edif 'fubar'
what you'll see is an editor screen containing just
3×⍳⍵
The for-completeness lambda-creation mode can be had by abusing the axis
argument:
edif [1] 'fubar'
Further (not that many people will care),
edif [2] ''
will show the edif version:
APL editor native function 2.2.0
and
edif [3] ''
will show git version information
