i have been using the pattern: 
s/(?<!\\)(\$[a-zA-Z0-9_]+)/whatever()/ge;

[download]
to replace all instances of non-escaped variable names in a source file with the output of whatever(). would there be any way to extend this pattern to NOT match $something[x] (so a scalar name followed by an array subscript, as that actually refers to an array, not a variable)..so basically look at ahead or something and ignore the pattern if its followed by a '['. thx.
