@custom xxx("...",<{...}>,...) : ＠custom can let users write own syntaxs. it is a transpile-time pattern-driven code generator with nested templates, namespace-scoped features "..." can generate code, <{...}> is similar to it but will become a placeholder and replaced by parameter when the custom syntax is called. Code will generate in global and the inner of some cppsp keywords. namespace only accept one level like: namespace n{ @custom.... }
