Does anyone have experience with this?

Specifically, I want to use a blueprint for a class that takes an
argument to new, but calling make (even with an argument) causes an
error.

Example:
class MyClass
def initialize(str)
...
end
end

MyClass.make
#or
MyClass.make('a string')
#or
MyClass.make('new' => 'a string')

Output:
wrong number of arguments (0 for 1)

Thanks.

Sean

Can you show the source for your 'make' class method? The following
works for me:

class MyClass
def self.make(*args)
new(*args)
end
def initialize(str)
@str = str
end
end
MyClass.make("hello")

Make is a method added to Object by the gem. It did not support
objects that take arguments to new. I added the functionality at
http://github.com/lotusone/machinist.

Thanks!
