The extra performance hit is because, possibly, the extra C function call and C stack massaging. Something to think about.

Here the performance penalty is 13% for the version that calculates linenumbers in each function call, and 3.5% for the memory spending extra memory for performance. The extra performance hit is because, possibly, the extra C function call and C stack massaging. Something to think about.
