Spreadsheet plugin LISTEACH and nested function formulas

-- BramVanOosterhout - 25 Jan 2016 The code:

 %CALCULATE{ "$LISTEACH(
               $item: $DEC2HEX($COUNTSTR( au.fujitsu.com, au.fujitsu.com, gmail.com, au.fujitsu.com, eaglet.rain.com, au.fujitsu.com, $item  ),6),
               au.fujitsu.com, gmail.com,  eaglet.rain.com )" 
}%

Produces: 6): $DEC2HEX(0, au.fujitsu.com: $DEC2HEX(4, gmail.com: $DEC2HEX(1, eaglet.rain.com: $DEC2HEX(1

The above demonstrates that a straightforward implementation of listeach with a nest function formula appears to parse the bracketing incorrectly. The second parameter of DEC2HEX (...,6) [the ,6)] is taken as the first entry in the list defining EACH in the listeach.

The sequence below shows that the functionilty works in non-nested funtions.

Is there a way to escape the nesting so that the parsing will behave correctly?
