Why do you say that? It is trivial to get around this limitation, but
it seems that block calls like this in expression position would just
look even weirder than the form where you have the block inside the
parentheses. Compare
let sum = reduce({|a, b| a + b}, myseq) + 2;
let sum = reduce(myseq) {|a, b| a + b} + 2;
Do you prefer the second? I figured this would just be a trick to make
statement-style loops look better.
Not in this example, but I always want nicer ways to write spawn.
Imagine a glorious future where spawn looks like
let task = spawn {
... do something ...
}
Yeah? Obviously there are a number of changes required to make that
possible.
Regardless, putting the block in parens isn't a major headache (except
that rust-mode and the pretty-printer don't like it).
