Subject: [ruby-talk:9959] Dynamically instantiating a class (with a string)

I know I could (and probably should) do this with some kind of a factory
pattern...

In Perl I can instantiate an object using a string that contains the name
of that object, like so:


$PLATFROM = "PC";
$myPCTool = "Tool$PLATFORM"->new(blah...);
#later:
$PLATFORM = "UNIX";
$myUnixTool = "Tool$PLATFORM"->new(blah...);
#where I have a class called ToolPC and another called ToolUNIX which
#inherit from Tool.

I kind of like this capability, is there any way to do something like that
in Ruby?
