In general, to_s and inspect on a tainted object should result a tainted string.
Range seems the only exception.

code

p ("0".taint.."1").to_s.tainted?
p ("0".."1".taint).to_s.tainted?
p ("0".."1").taint.to_s.tainted?

expected result

prints true 3 times.

actual result

prints true, true, and false.
