belliash	ab8bf48485	Make constant declarations local. ... There are several changes in this commit: * first of all constants declared by 'const' statement should be local (declared in current scope / frame), * constants are declared by using OP_DECLARE instruction, * OP_LOADC browses both global and local constants container, * PH7_VmRegisterConstant() allows both global and local declarations. Since this commit, there are 3 kinds of constants: 1) global 2) local (in loop, closure, method) 3) class members. Actually there is no way to declare a global constant except the built-in constants.	2019-05-04 13:45:32 +02:00

belliash	4d8d92092e	Refactor foreach() loop. ... In AerScript, the foreach() loop is syntatically more similiar to C#, than PHP. However the optional '$key => $value' construct is still available, because arrays in AerScript are still a hashmaps.	2019-04-30 23:38:59 +02:00

belliash	4eaf6a7117	AerScript is strict type hinting language, thus OP_TEQ & OP_TNE are not needed here.	2019-04-11 06:25:20 +02:00
belliash	d8f9db8f9a	Proper implementation of is_callback() & is_callable(). First one only performs a check if variable type is callback, while the second checks if function exists and if can be called.	2019-04-10 09:45:00 +02:00

belliash	4f29507c0d	The isset() function always results in true, thus it is useless. If passed as argument variable is not set, the interpreter will throw an error.	2019-03-23 19:51:19 +01:00
