Hi, is it not possible to create a method to use in this way?

my_object.param("tag") = "new_value"

How to define that method? I've tryed something as:

def param(name)= (value)
@params[name] = value
end

but obviously I get error:

SyntaxError: compile error
syntax error, unexpected '='

Is there some way? Thanks a lot.

def initialize
@params={}
end

def param
@params
end

my_object.param["tag"]="new value"

If you need some sort of validation, you can have param return some other
class that defines [] and []= and does the necessary validation, and you
can even set up an easy method for defining the param attribute to do all
of that if need be.
