One of the coolest features of `modernize` is that it turns a series
of string appends into a strings.Builder + WriteString() statements.
This is more efficient because it avoids allocations.
However I notice that if the append is multiple strings (s += a + b)
the transform results in allocations:
- s += "foo" + myvariable
+ s.WriteString("foo" + myvariable)
Would it be more efficient to rewrite it as 2 statements:
+ s.WriteString("foo")
+ s.WriteString(myvariable)
Is this worth filing a feature request or is the potential improvement
negligible?
