New issue 4183 by [email protected]: Tagged template incorrectly restricted
from CallExpressions
https://code.google.com/p/v8/issues/detail?id=4183
Template tag references may be derived from MemberExpressions or
CallExpressions, but V8 does not support the latter:
$ d8 --harmony -e '(function() { return print; })()``'
unnamed:1: SyntaxError: Unexpected template string
(function() { return print; })()``
^^
SyntaxError: Unexpected template string
from ES6 12.3.7.1 (Tagged Templates, Runtime Semantics: Evaluation) [1]:
MemberExpression : MemberExpression TemplateLiteral
1. Let tagRef be the result of evaluating MemberExpression.
2. Let thisCall be this MemberExpression.
3. Let tailCall be IsInTailPosition(thisCall). (See 14.6.1)
4. Return EvaluateCall(tagRef, TemplateLiteral, tailCall).
CallExpression : CallExpression TemplateLiteral
1. Let tagRef be the result of evaluating CallExpression.
2. Let thisCall be this CallExpression.
3. Let tailCall be IsInTailPosition(thisCall). (See 14.6.1)
4. Return EvaluateCall(tagRef, TemplateLiteral, tailCall).
