I once on a project where we couldn't use third party libs. We needed a substring search but the needle could be 1 of N letters. My teammate loves SIMD and wanted to write a solution. I took a look at all of our data and the most strings were < 2kb with many being empty and < 40 letters. SIMD would have been overkill. So I wrote a simple dumb for loop checking each letter for the 3 interesting characters (`";\n`)
