We need something more fine than --skip-badvars to tolerate
run-time errors associated with $expression evaluation.
Something like this:
try {
stmt1 ...
} catch (varname) {
stmt2 ...
}
semantics being: optional "varname" would get assigned the error
string, and stmt2 would be evaluated, should the stmt1 block be
departed due to an error (that sets context->last_error).
This would be used for $variable protection thusly:
for (i=0; i<100; i++) {
try {
println("%d", $var->field[i])
} catch {
println("oops")
# don't break to continue iteration; or break to leave early
}
}
