Today I was looking for the same thing. I cannot guarantee that this will not happen, but this is what I discovered.
src/node_extensions.h , :
ITEM(node_module_name)
module_name - ()
, , ,
NODE_MODULE(node_module_name,
, , evals process.bindings:
$ grep "NODE_MODULE(node_evals" src/*.cc
src/node_script.cc:NODE_MODULE(node_evals, node::InitEvals)
