valid(keyword)

the valid keyword is an expression that returns a constant expression bool.

the keyword will check if an expression or statements will throw an compile time error.

for example:

        |main[] -> void:
         bool DoesFuncExist = valid(:Func();); 
         $if DoesFuncExist:
          Console::Log("found func");

the varable "DoesFuncExist" is false because the compiler will detect that Func cant be found in the scope.

[!NOTE] The valid keyword only checks the statement or expression.the statement or expression will never execute the code at runtime.
