This is wrong in several important ways:

>> var = "abc {foo} def {bar}"
=> "abc {foo} def {bar}"
>> var.match(/({.*})/).captures
SyntaxError: compile error
(irb):2: invalid regular expression; there's no previous pattern, to 
which '{' would define cardinality at 2: /({.*})/
  from (irb):2

>> var.match(/(\{.*\})/).captures
=> ["{foo} def {bar}"]
>> var.match(/(\{.*?\})/).captures
=> ["{foo}"]

What I think you're looking for is:

>> var.scan(/\{.*?\}/)
=> ["{foo}", "{bar}"]
