" Seems like a bug."

But note [U], p. 209:

" Finally,

local i++

will not increment the local macro i but instead redefines the local macro i
to contain ++."

Betreff: st: increment operator

Is the behaviour of the following to be expected?

  local C = 0
  forv i=1/10 {
	di "`C'"
	local C++

I know the increment operator is ++C, but inadvertently used this
instead and could not track down the error for quite a while, because
it even produced integer values in places. Seems like a bug.
Especially as trailing ++ is allowed in expansion operators:

  local C=0
  forv i=1/10 {
	di "`C++'"

works just fine.
