In computer science, yes. In perl (surprise!) no.
----------------------\/--------BEGIN---------\/----------------------
% perl -lwe '$x = "hi";'
Name "main::x" used only once: possible typo at -e line 1.
%
% perl -lwe '$x = "hi"; $x = "lo"'
%
% perl -lwe '$x = "hi"; print $x'
hi
%
----------------------/\---------END----------/\----------------------
I don't know what is causing Ranga's warning. But it is not
LHS-versus-RHS.
