                Simplified algorithm for detection of strict-mode errors in ECMAScript 6.
              
          
    A context object is associated with any AST node which may have "strictness".  Each context has a strictness state:  UNKOWN, STRICT, and NOT_STRICT.  In order to account for arrow functions, parenthesized expressions are also assigned a context.
When a context C is pushed:


set C.parent to the current context object
set C.strictError to null
if C.parent.strict is STRICT

set C.strict to STRICT


else
set C.strict to UNKNOWN
