In 11.5.2 the query 

  range x from 0 to 5 step 0.5

generates this tree

 List: range x from 0 to 5 step 0.5: 
  SeparatedElement: range x from 0 to 5 step 0.5: 
   ExpressionStatement: range x from 0 to 5 step 0.5: 
    RangeOperator: range x from 0 to 5 step 0.5: (x: real)
     NameDeclaration: x: 
      TokenName: x: 
     LongLiteralExpression: 0: long
     LongLiteralExpression: 5: long
     RealLiteralExpression: 0.5: real

In 11.5.3 the RangeOperator incorrectly infers that x is long...

 List: range x from 0 to 5 step 0.5: 
  SeparatedElement: range x from 0 to 5 step 0.5: 
   ExpressionStatement: range x from 0 to 5 step 0.5: 
    RangeOperator: range x from 0 to 5 step 0.5: (x: long)
     NameDeclaration: x: 
      TokenName: x: 
     LongLiteralExpression: 0: long
     LongLiteralExpression: 5: long
     RealLiteralExpression: 0.5: real

This is fixed in 11.5.4
