puts does an implicit to_s on anything you pass to it, so you don't actually
need to do that explicitly.

Careful here. This is the same as

  puts @myvar=("string".class.to_s)

i.e. you are assigning "String" to @myvar, not "string".

Again, here the @myvar instance variable of 'a' now contains string "Fixnum"
