String -> symbol

ok - i'm officially an idiot.

i want to dynamically alias the names of all methods in a module... i need to string-manipulate the original method name to get the new one. alias_method only takes symbol names and the only tricks i know to convert strings to symbols (i.e., method("this_func") and SomeClass.method_eval("this_func) don't apply.

  my_module.instance_modules.each{ |m|
     m_new_name = <string stuff on m>
     alias_method <what goes here?> <and what goes here?>

more generally, is there some easy way to convert strings to symbols that i've missed?

thanks

Is String#to_sym (or String#intern) what you looking for?

alias_method only takes symbol names

That isn't true. alias_method takes strings just fine:

>> class A; alias_method 'foo', 'to_s';end; A.new.foo
# => "#<A:0xb7cfcf08>"

Which one is in fact preferred?

Either one, they are synonymous.
