initialization by non constant value at declaration of variable statement

[r-koubou]

[EXPECT]

on init
    declare $i := 0 {OK: 0 is constant value}
    declare $k := get_engine_par( $ENGINE_PAR_VOLUME,-1,-1,-1 )
    {NG: Command may returns non constant value}
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
end on

[NOW]

on init
    declare $i := 0 {OK: 0 is constant value}
    declare $k := get_engine_par( $ENGINE_PAR_VOLUME,-1,-1,-1 )   {OK: Allowed}
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
end on

Done.
It going to be contained in vsce 0.4.1.

Reopen.

By behavior of KONTAKT is unknown, errors are currently erroneously detected. I will adjust.

[r-koubou]

Plan of fixes:

1. Allow initialization by non constant values. == rollback to previous version's behavior.

2. Constant variable: deny initializer by return value of KSP command.

declare $X := num_element( %ARRAY ) {OK}
declare const $Y := num_element( %ARRAY )
{
    NG: Because KSP built-in command returns value will maybe undefined
    until running script on KONTAKT. Compiler cannot detect it.
}
