String indices in loops yield "empty expression"

[numeredev]

DESCRIPTION

Describe the bug If string indexing of table columns is used within loops, then an "empty expression" error is thrown.

To Reproduce Steps to reproduce the behavior:

1. Create a table
2. Assign headlines to the columns
3. Try to assign values to those columns using string indices in loops
4. See error

new tbl()
tbl(#, :) = {"COL1", "COL2"};
for (i = 1:10)
    tbl(i, "COL1") = i^2;
endfor

Expected behavior The string indices work as regular numerical indices

Seems to be already fixed by some other change. Error is reproducable in last release but not present anymore in current dev version.
