[Bug-apl] Local variables in lambdas

[Juergen Sauermann]

Hi,

Thinking about lambdas once more I had an idea of a syntax for declaring local variables in
the lambda. In order to bring lambdas and proper functions closer together rather than separating
them more than necessary, we could use the same syntax as in proper defined functions: a list
of variable names separated by semicolons. A lambda with body ⍺+⍵ and local variables C, D,
and E would then be declared as:

      {⍺+⍵;C;D;E}

One could also think of

      {C;D;E;⍺+⍵}

But the first looks more appealing to me. Any opinions?
