Although not alternative syntax, the below notations work as expected: ["A","B","C"] # 1; //B ["A","B","C"] #1; //B ["A","B","C"]#1; //B ["A","B",["C","D"]]#2#0; //C

Here is an example of what higher precedence means: [1,2,3,4] select 2/2; // divides 2 with 2, therefore selects second element = 2 [1,2,3,4] select (2/2); // same result with brackets [1,2,3,4] # 2/2; // selects third element, then divides by 2 = 1.5 ([1,2,3,4] # 2)/2; // same result with brackets
This operator can not be used in conjunction with the #define preprocessor.
#define SEL_ERR [0,1,2]#0 //error #define SEL_NOERR [0,1,2] select 0 //works

Beware new-lines when using this operator. I suspect the preprocessor to fail. The following code will not compile without throwing an error: [0] # 0;
