problem with for...in

[David A. Bayly]

This is an old and annoying glitch. You get item#1 when you open the 
table in the IDE, perhaps there are other circumstances too, but 
that's the major one.

One work-around better than testing in the loop.


try {delete(@myTable.["item #1"])}
for adr in myTable {
	adr^.myValue = "this string"}
