Stated the Groovy documentation a Gstring can be resolved both in a eager and lazy manner: def number = 1 def eagerGString = "value == ${number}"def lazyGString = "value == ${ -> number }" assert eagerGString == "value == 1" assert lazyGString == "value == 1" number = 2 assert eagerGString == "value == 1"assert lazyGString == "value == 2" http://groovy-lang.org/syntax.html#_special_case_of_interpolating_closure_expressions The example you are reporting should *already* be reasolved eagerly and I can agree that it can be confusing. However the ability to resolve a GString lazily it's a very important Groovy feature for DSL builders. Wipe it out would have a serious impact (read destroy) on existing frameworks that rely on that feature.
