While Loop does not evaluate exit condition (when using Dollar-Sign)

Environment:
Qlik Sense and QlikView all versions

When a script is using a loop and the condition evaluates a variable with a Dollar-Sign expansion the loop never stops:
As an example:

set vCount= '0'; 

do while $(vCount) <= 3 
Let vCount = $(vCount)+1; 
Trace vCount: $(vCount); 
loop 

exit script; 


This Script never stops execution even if the condition is fulfilled.

The combinations (and possibilities) are almost limitless due to the very flexible implementation of variables, but this comes at the price of simplicity. It is recommended to read up on all chapters concerning "dollar-sign" expansions. 

There is no inconsistency with the dollar-sign expansion of variables, but the implementation is highly flexible in order to allow variables to be expanded at several different levels. On top of this there is the added complexity with all Boolean functions returning a dual result with both a text-representation and a numeric value (where “-1” equals true and “0” equals false). 

The use of the Dollar-Sign expansion while evaluating a condition (Boolean) is not the most appropriate. Dollar-sign expansions are definitions of text replacements used in the script or in expressions. 
As per R&D this is working as designed.

In order to make this script work just remove the Dollar-Sign expansion char in the while condition:

set vCount= '0'; 

do while vCount <= 3 
Let vCount = $(vCount)+1; 
Trace vCount: $(vCount); 
loop 

exit script;
