This is what I'm trying to do:
这就是我想要做的:
def call_block(in_class = "String", &block)
instance = eval("#{in_class}.new")
puts "instance class: #{instance.class}"
instance.instance_eval{ block.call }
end
# --- TEST EXAMPLE ---
# This outputs "class: String" every time
"sdlkfj".instance_eval { puts "class: #{self.class}" }
# This will only output "class: Object" every time
# I'm trying to get this to output "class: String" though
call_block("String") { puts "class: #{self.class}" }
