Why do we need these two separate variables instead of using True(isolate) and False(isolate) inline like before?

Local<Boolean> false_value = False(isolate);

Local<Object> obj = Object::New(isolate);
#if defined(DEBUG) && DEBUG
Local<Boolean> debug = trueValue;
Local<Boolean> debug = true_value;
#else
Local<Boolean> debug = falseValue;
Local<Boolean> debug = false_value;

Instead of making this change multiple times, what if we instead removed the temporary variables instead and just set the values directly in the obj->Set() calls? For example:

obj->Set(FIXED_ONE_BYTE_STRING(isolate, "debug"),
#if defined(DEBUG) && DEBUG
         True(isolate)
#else
         False(isolate)
#endif
        );

or something similar or maybe even write a macro for this?

#endif // defined(DEBUG) && DEBUG
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "debug"), debug);

obj->Set(FIXED_ONE_BYTE_STRING(isolate, "uv"), trueValue);
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "uv"), true_value);
// TODO(bnoordhuis) ping libuv
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "ipv6"), trueValue);
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "ipv6"), true_value);

#ifdef TLSEXT_TYPE_application_layer_protocol_negotiation
Local<Boolean> tls_alpn = trueValue;
Local<Boolean> tls_alpn = true_value;
#else
Local<Boolean> tls_alpn = falseValue;
Local<Boolean> tls_alpn = false_value;
#endif
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "tls_alpn"), tls_alpn);

#ifdef SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
Local<Boolean> tls_sni = trueValue;
Local<Boolean> tls_sni = true_value;
#else
Local<Boolean> tls_sni = falseValue;
Local<Boolean> tls_sni = false_value;
#endif
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "tls_sni"), tls_sni);

#if !defined(OPENSSL_NO_TLSEXT) && defined(SSL_CTX_set_tlsext_status_cb)
Local<Boolean> tls_ocsp = trueValue;
Local<Boolean> tls_ocsp = true_value;
#else
Local<Boolean> tls_ocsp = falseValue;
Local<Boolean> tls_ocsp = false_value;
#endif // !defined(OPENSSL_NO_TLSEXT) && defined(SSL_CTX_set_tlsext_status_cb)
obj->Set(FIXED_ONE_BYTE_STRING(isolate, "tls_ocsp"), tls_ocsp);
