Just from looking at the hello world example, I don't like how "say" and "ask" are placed at the end. It would be much more readable to start with that.
The language's developers themselves seem to agree that postfix syntax isn't always best: The syntax for the type "list of characters" is "List<Char>", which is not postfix. Compare ML-family languages, where this would use postfix syntax, writing this type as "char list".
That may be the case, but taking a core language feature and commenting "I don't like it, change it" isn't a very effective way to encourage discussion, in my opinion.
Anyway, here's a rough idea. Introduce some special token, like : for example, and add a special syntax rule in the parser that "a: b" is parsed as if it had been written "b a".
Then people who find it more readable can write
say: "hello"
"hello" say
We can have discussions about the convenience or readability of different syntaxes, but if the arguments are going to be of the level of "I don't like it", then a downvote is a valid response.
So it's always: data => process => process => process.
Left to right, no surprise, always the same thing first.
I kinda like the idea, although it's weird to get used to due to unfamiliarity.
