/** Used to indicate a variable number of parameters for the Function Wizard.

    VAR_ARGS if variable number of parameters, or VAR_ARGS+number if number of
    fixed parameters and variable arguments following.

    @see formula::ParaWin
    @see ScFuncDescCore

    @NOTE: the value can't be easily changed. If changed then
    reportdesign/source/ui/misc/FunctionHelper.cxx
    FunctionDescription::getVarArgsStart() has to provide some backward
    compatibility for implicit API stability.
    The new VAR_ARGS value must be significantly greater than the old
    PAIRED_VAR_ARGS (2*VAR_ARGS) value, in fact greater than any used number of
    fixed parameters followed by optional paired parameters.

    @NOTE: also
    reportbuilder/java/org/libreoffice/report/pentaho/StarFunctionDescription.java
    uses a hard coded value in StarFunctionDescription::getArguments() for
    functionDescription.isInfiniteParameterCount() which though looks like it
    could be easily adapted.
