Get nested JSON object with GSON using retrofit
..."status":"OK",
"reason":"some reason",
"content" :
{
"foo": 123,

{
return v.empty();
}
bool foo2( const std::string & v )
{
return v.empty();

:!echo "current file: %"
current file: foo.c

But what's the point of passing the implicit parameter but not naming it? How can this be useful when implementing the method foo?
Often, the implicit paramet...
