Another issue with MarkupTemplateEngine in Groovy 4

Hi,

here is another issue, Groovy 4 MarkupTemplateEngine fails on map index
with name.

Failing:
  def a = [ 'b' : [ 'c' : 'd' ] ]
  def res = a['b']
  div { yield res }

See attachment for reference.

Failure is

index problem in GeneratedMarkupTemplate0
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
failed:
General error during instruction selection: size==0

1 error

Workaround:
  def a = [ 'b' : [ 'c' : 'd' ] ]
  def res = a.b
  div { yield res }


Best regards, Jörg
