So this is like dissecting a sentence into letters, and then checking if it contains a certain character, and if it does, it returns true?
I feel that you could easily make this with custom blocks: NO SUPPORT
Ok, maybe a little.

def substrMatches(haystack, needle, startIndex){ // boilerplate sub-function
    // I built some other string functions off of this as well such as replace and split
    for(j=1;j<=lengthOf(needle);j++){
        if(!(letterAt(j+startIndex - 1, haystack) == letterAt(j, needle))){
            return 0;
        }
    }
    return 1;
}
def strContains(haystack, needle){ // actual function
    for(i=1;i<=lengthOf(haystack)-lengthOf(needle);i++){
        x = substrMatches(haystack, needle, i); // upper function needed here
        if(x == 1){ return 1; }
    }
    return 0;
}

How about

(position of [substring] in [epic substring plus some more stuff]::operators) // returns -1 for not found, 1 to length(2nd param) if found
(slice [epic string] at (2) to (3)::operators) // same as substring() in JS/Java/PHP/etc
<is uppercase [l]?::operators> // true if the letter is uppercase, otherwise false
([epic string] as all [uppercase/lowercase v]::operators)
// and how about byte/char conversions for hash functions
(number (67) as character::operators)
(letter [s] as number::operators)

I could go on and on…

Yes, this would be an ideal operation for a custom operator or function.

No, I mean a custom operator or function. We already have a custom reporter – variables.
