[JEXL-181] Cannot create inline Map with array or function call as the key

Description

It seems that inline maps can be created only if:

• the keys are string literals or a numbers
• the keys are variables

The followings throw exception:

{ ['1', '2'] : someValue }
{ myVar.callFunction() : someValue }

Example stacktrace for expression:

{ 'step'.toString() : [1, 2] }
