> Starting with 2.4.7, performance in string processing (in certain scenarios) 
> has decreased dramatically. Specifically, it happens when using 
> {{stripMargin()}} on a {{GString}} that has a variable substitution with a 
> huge String value. In our app performance decrease was from tens of 
> miliseconds to 1+ minute. 
> I suspect the latest refactoring in string methods.
> Attaching a test case.
