Hi Martin,
to my knowledge the parenthesis work in general, with the exception of passing 
parenthesis into the d2:condition() function: DHIS2-2813 
<https://jira.dhis2.org/browse/DHIS2-2813>

You would be able to write parenthesis in program indicators expressions and 
filters. What is not supported is nested d2: function calls. 

Please report if you experience problems with parenthesis outside the known 
issue above.
