Can it be nested? Haskell's do can be used like
do
r <- do
foo
bar
quux r
But I don't see (from https://gleam.run/news/v0.25-introducing-use-expressions/ https://gleam.run/news/v0.25-introducing-use-expressions/) any obvious way of nesting like that in Gleam.
- lpil 3y agoUnlike in Haskell `{}` are not optional in Gleam, so that would be written like so: use a <- one({ use b <- two // etc })
- tome 3y agoThanks. I don't fully grasp what `one` is, but do notation has the nice property that do r <- do foo bar quux r is the same as do foo r <- bar quux r It doesn't look like that holds for use. Specifically one({ use b <- two foo }) baz is not the same as use b <- two foo baz right?
- lpil 3y agoCorrect, it’s not.
