static scope การใช้

• In programming languages with static scope, alpha-conversion can be used to make alpha renaming to make name resolution trivial ).
• Correct implementation of static scope in languages with nested functions are used, although there are well-known techniques to mitigate this.
• Its influence lives on in various other systems however; the Java's parametric types solve some of the same problems of uninstantiated types escaping from their static scope.
• Using my in this case instead of local would have printed 1 three times since in that case the $ a variable would be limited to the static scope of the function and not seen by.
• In " lexical scoping " ( or " lexical scope "; also called " static scoping " or " static scope " ), if a variable name's scope is a certain function, then its scope is the program text of the function definition : within that text, the variable name exists, and is bound to the variable's value, but outside that text, the variable name does not exist.
