I've also liked the idea that the unambiguous expression text:upper
becomes a partial function application creating a new closure[1]; it's
convenient for callbacks.  (text:upper() continues to be evaluated
directly, of course)

As for 'v: integer' as an expression: it looks very much like a
dynamic _typecast_ and I would probably write it as "v as integer".

"HELLO"

Note the ugly \ for method calls and the idiomatic ! for calling a
function of no arguments.
