i am writing code that will go through a source file and replace all variable names with the output of a subroutine called rvg(). rvg() has random output, and everything works fine, but i would like the code to replace all instances of the same variable name with the same rvg output...but it doesnt seem to work. the relevant code is: 
$/="";
while(<FILE>) {
s/(?<!\\)(\$\w+(?![\[{\w]))/rvg()/ge;
print;
}

this works great on something like "$v1 $v2"...but if FILE contains something like "$v1 $v1", it gets replaced with like "$ghFjgjf $ldkSmd" instead of "$ghFjgjf $ghFjgjf" which is what i would have hoped. ($/ is set to "" so it only takes one pass to get through FILE, and i used /g for the regex so all instances of the matched pattern are substituted, to no avail)
