[Swift-devel] file declaration inside foreach

[Mihael Hategan]

That with the assumption that k[i-1] would work.
It seems that k[i] = k[i-1] + i gets translated into this:
assign(dpath="[i]", dvar=k, 
  svar = sum(getFieldValue(var=k, path=concat("[]")), getFieldValue(i))
)

Seems like k[i-1] is translated into the wrong thing there
(path=concat("[]")).
This comes from the fact that paths like [i] are passed directly instead
of the value being extracted.

Yong, do you remember why we did this?
