How to convert hashed parameters to local variables?

Closest I can get is :

require ‘ostruct’

def announce args
parameterise( args, :age=>21 ) do |template|
“My name is #{template.first} #{template.last} and my age is
#{template.age}”
end
end

def parameterise args, defaults, &block
args = defaults.update args
template = OpenStruct.new( args )
block.call( template )
end

puts announce( {:first=>‘John’, :last=>‘Smith’} )

What I desire is an implementation for “parameters” such that:

def announce(args)
parameters(args,:age=>21)
“My name is #{first} #{last} and my age is #{age}”
end

announce(:first=>‘John’, :last=>‘Smith’) generates
“My name is John Smith and my age is 21”
