Example

Make file with content inside

Read file, make content upper case, write back

file.read :sample.txt $> string.upper $> file.write :sample.txt
print (file.read :sample.txt) ;; SOME TEXT HERE

Make curried writer and reader

let file.reader (fn [name] (fn [] file.read name))

let write (file.write :sample.txt)
let read (file.reader :sample.txt)

write :hello
call read ;; (zero args function must be called via `call` fn) "hello"

call read $> string.upper $> write $> call read ;; HELLO

Count of lines in all *.rs files in src

file.glob :./src/**/*.rs $>
  list.map file.read $>
  list.map (fn [c] string.lines c $> list.len) $>
  list.sum $>
  print
