synopsis: Hasql extension for dynamic construction of statements
description:
  Library extending Hasql with a composable API for building SQL statements dynamically.

  The core abstraction is 'Snippet', which allows you to construct SQL statements with parameters
  injected in-place, automatically handling placeholders and encoder matching. This is particularly
  useful when the structure of your SQL depends on runtime parameters.

  Key features:

  * Composable SQL snippets using 'Semigroup' and 'Monoid' instances
  * Automatic placeholder generation and parameter encoding
  * Type-safe parameter injection with implicit encoder derivation
  * Protection against common SQL construction bugs
  * Support for conditional SQL structure based on parameters

  Example:

  > selectSubstring :: Text -> Maybe Int32 -> Maybe Int32 -> Snippet
  > selectSubstring string from to =
  >   "select substring(" <> param string <>
  >   foldMap (\x -> " from " <> param x) from <>
  >   foldMap (\x -> " for " <> param x) to <>
  >   ")"
