When logging or showing messages I often use Template parameters. Quite often they are of a different type than string. Now it is required to cast this data type explicitly to a string using either the toString() function or by appending a string. It would save me some time and would also make the model easier to read if Mendix can cast the Integer to a String. This is a technical step for which the user should not be bothered in my opinion.
So instead of
$Count + ''
or
toString($Count)
just allow me to write
$Count
