boolean, defaults to false.
When true, tagged template literal objects aren't frozen. All template literal expressions and quasis are combined with the + operator instead of with String.prototype.concat.
When false or not set, all template literal expressions and quasis are combined with String.prototype.concat. It will handle cases with Symbol.toPrimitive correctly and throw correctly if template literal expression is a Symbol(). See babel/babel#5791.
In
