1235455 - Calling a higher order function returns "function a/<()"

Status: RESOLVED INVALID

(DevTools :: Console, defect)

Description

[giul.mus]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20151208100201

Steps to reproduce:

I ran the following code in the Javascript console:

var a = b => c => c; /* (or equivalently a = function(b) { return function(c) { return c; }} */
a(1);


Actual results:

The console returned "function a/<()", which is a syntax that I'm completely unaware of.


Expected results:

I expected the result to be something like "function()" or "function a()".

fwiw, the naming rule itself is described in bug 433529 comment #7 and bug 433529 comment #9.
