Parsers combinators with F#6 [<InlineIfLambda>]

Thanks to manofstick peer reviewing the blog post.

Full source code at github

For F# Advent 2021 I wrote a blog post exploring how F#6 [<InlineIfLambda>] can improve data pipeline performance.

I was thinking of other places where [<InlineIfLambda>] can help and decided to try to build a parser combinator library with [<InlineIfLambda>].
