In math we also have the set-notation like:
A = { a | a > 0 }
which means something like: A is set of elements,
greater then 0... and so on. This could also
be read similar to block-syntax. We get a set of elements
on which we perform some operations (like map+lambda
call in funcional languages, anonymous function +
set of elements).
