std::string	nk::builtin::nk::envGet (const char *name)
void	nk::builtin::nk::envSet (const char *name, const std::string &value)
void	nk::builtin::setenv (const std::string &name, const std::string &value="")
	Sets or clears an operating system environment variable (setenv(name, value)).
std::string	nk::builtin::getenv (const std::string &name)
	Reads an operating system environment variable as a C++ string (getenv(name)).
Value	nk::builtin::getenv (const Value &name, std::pmr::memory_resource *mr=nullptr)
	Reads an environment variable returning a character row Value (val = getenv(name)).
bool	nk::builtin::iskeyword (const std::string &name)
	Tests whether a string is a reserved MATLAB language keyword (iskeyword(s)).
const std::vector< std::string > &	nk::builtin::keywords ()
	Lists all reserved MATLAB keywords as a C++ vector.
Value	nk::builtin::iskeyword (Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
	MATLAB-compatible overload for iskeyword.
bool	nk::builtin::isvarname (const std::string &name)
	Tests whether a string is a valid MATLAB variable name (isvarname(s)).
Value	nk::builtin::isvarname (const Value &name, std::pmr::memory_resource *mr=nullptr)
	MATLAB-compatible overload for isvarname.
Value	nk::builtin::isvarname (Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
	Span-based MATLAB-compatible overload for isvarname.
