Writing programs to use static methods but still compile in IDL 7 [message #91803]

I am trying to update my code to use the static methods introduced in IDL 8.4 when the user has V8.4 or later. So I write a statement like the following

if !VERSION.RELEASE GE '8.4' then return,str.replace(in,out)

This works in IDL 8.0 and later but in IDL 7.1.1 and earlier it gives a compilation syntax error.

compile_opt idl2
if !VERSION.RELEASE GE '8.4' then return,str.replace(in,out)
% Syntax Error. Attempt to subscript array with parenthesis. Please use '[]'.

Is there a way to have a program use the static methods when the user has IDL 8.4 or later without causing a compilation syntax error in IDL 7?

An example program is

Thanks, --Wayne
