ReproducibleScript:
# FILE: test.tcl
    puts stderr [info patchlevel]
    break

ObservedBehavior:
$ tclsh8.0 test.tcl
    8.0.5
    invoked "break" outside of a loop
        while executing
    "# FILE: test.tcl
    puts stderr [info patchlevel]
    break
    "
        (file "test.tcl" line 1)
    
    $ tclsh8.1 test.tcl
    8.1.0

DesiredBehavior:
Ideally, consistent error messages between 8.0.x and 8.1.x Tcl releases.
    
    At a minimum, there should be some error message reported by Tcl 8.1.x.



Verified in 8.2.0.  Returns an empty line.

Hmm.  The problem is not that the [break] isn't having an
effect, but rather
that no error message is being generated.  See the following
session:

$ cat test.tcl 
# FILE: test.tcl 
puts stderr [info patchlevel] 
break 
puts stderr "FELL THROUGH"
$ tclsh8.3 test.tcl 
8.3.2

$ tclsh8.0 test.tcl 
8.0.4
invoked "break" outside of a loop
    while executing
"# FILE: test.tcl 
puts stderr [info patchlevel] 
break 
puts stderr "FELL THROUGH"
"
    (file "test.tcl" line 1)
$ tclsh8.3
% source test.tcl
8.3.2
invoked "break" outside of a loop

Note first that neither 8.0.4 or 8.3.2 fell through to the
rest of the script, so the break itself must have worked. 
Second, note that there is an extra blank line generated
after the printing of the patchlevel under 8.3.2, so
something is coming of the break.  It looks to me like this
is actually either a problem with Tcl_EvalFile or with the
default error handler in 8.3.2, and this problem is not
exercised when running interactively...

Not sure when this got fixed, but it works identically in 8.0.4 and 8.3.2, so I'm closing this one.
