inline lambda issue Topic is solved

@Lexikos, I LOVE the high-order functions / lambda support you've added. I know some say scope creep... I say pure genius! Love it.

I'm having a little trouble with the following. I've implemented a functional fold method in my custom list class that overrides Array() and []. I won't post that code here, except for the method itself. I think this is the fairly standard fold algorithm:

Code: Select all

 fold(ini, opr) {   ; fold list beginning with ini; applying operation opr sequentially to result of prior
    acu := ini                               ; accumulator gets initial value
    for idx, itm in this                     ; loop list
      acu := opr.call(acu, itm)              ; operation on prior acu and item
    return acu                               ; return final state of accumulator
  }

When I call it, this works:

Code: Select all

  lst := [20,30,10]
  fnc := (a,i) => a+=i
  msgbox lst.fold(5, fnc)

but this doesn't:

Code: Select all

  lst := [20,30,10]
  msgbox lst.fold(5, ((a,i) => a+=i))

It fails with Error: Missing operator or space before "(".
Am I violating a syntax rule by putting the lambda in the fold call directly?

EDIT: msgbox lst.fold(5, (fnc(a,i) => a+=i)) works too...

Helgef had already reported this issue. It's fixed in v2.0-a092.

Apologies for the duplicate. I've tested and can confirm this and similar behavior fixed in v2.0-a092. You're sure quick with the updates. Many thanks.
