In Go, sure. In Haskell, for some app use-cases (and I believe static-site-gen is one such) it takes endless patience and tweaking to reach on-par performance with let's say "systems languages". There's scenarios where Haskell's lazy-evaluation may save a running program a lot of unnecessary work theoretically, but in practice I found there's not too many, compared to any eagerly-evaluated program written by a not-a-total-newbie-programmer. Certainly not such batch text-file processing. Then you'd easily parallelize your Go program wherever it makes sense, which in Haskell I didn't do but relied on whatever magic the compiler sprinkles in (if any) via compiler-options =) Also I'm having a rather excessive template system there! As long as it doesn't take 20s for 20p.. or I have to manage 10-100k-page sites..
