Range `for`

The general declaration of a for loop in C like for (init; condition; step) will be removed. Instead, for loops shall only (ONLY!) be used for range based loops only:


    NAL:
    for (i in myArray) {...}
    for (i in [5 .. n]) {...}


    C:
    for (size_t i = 0; i < _nalArraySize(myArray); ++i) {...}
    for (size_t i = 5; i < n; ++i) {...}

Syntax is similar to other languages like Python
Maybe even the round parantheses () can be removed? This is how it looks: for i in myArray {...}
Type of Index-Variable is absolutely clear.
The index variable is ALWAYS defined within the scope (even though it is written in the round parantheses). If the index shall become visible to the outside scope, one can use the bleed keyword.
More complex loops have to be programmed with while.
