I obviously thought I did.

Perhaps Comment #2 explains what happened?  If not I will check.

Whats the Swift logic regarding recompilation if it finds an existing 
.kml file? Does that logic get fooled in some cases?

It seems that if I remove the .xml and .kml files from previous 
compiles, this
problem goes away, and I get instead the message that I was trying to debug
originally:

Compile error in foreach statement at line 18: Compile error in procedure
invocation at line 19: variable a is not writeable in this scope

(the line numbers here dont match the source code in the URL filed here 
because
Ive changed things since then in the course of debugging).

The attached code compiles and runs without error for me.

Note that there appears to be no variable 'a' referred to in that source 
file
at all. If you continue to have problems, please attach code and error 
messages
that actually belong together.
