Re: [Bug-apl] This looks wrong

Hi,

my point is that there should be no difference between lambdas and defined functions.

The reason that the left argument is ignored is that dyadic functions can be called monadically
(the presence of the left argument can be checked with ⎕NC but it does not have to be checked.)
But even in this case lambdas and defined functions behave in the the same way.

What you are arguing for is that lambdas and defined functions shall behave differently
in the niladic case. This maybe convenient at times but would increase the complexity
of the syntax and could come as a surprise for many others

Right. Even in GNU APL monadic lambdas consume and ignore any left
argument you give them, so you could argue that it's consistent for
niladic lambdas to consume and ignore both arguments.

And, one could argue that knowing that lambdas are always variadic is quite
consistent in itself.
