defining functions in object comprehensions

[gurer-kensho]

I have encountered following corner case in one of our jsonnets:

Input:

local funcs = {
  [a](x): x * 2
  for a in ["f1", "f2", "f3"]
};
funcs.f1(10)

Official jsonnet output:

20

Jrsonnet output:

syntax error: expected one of "(", ".", "[", "{", "}", <binary op>, got "f"
    gurer.jsonnet:3:3

One way to avoid this is to use [a]: function(x) x * 2 form which works in both implementations and a cleaner form anyway. But I'd wanted to report this just in case.
