By an accident - mixins are not hygienic.
Do you use other people's source code without reading the
documentation or reading the source code?
Yes, all the time. Documentation is always lacking and reading
full 10 MLOC code base to tweak a single function is never an
option.
How would the author of "updateGui()" know that you named your
variable "st"?
He has no idea how you may name your variables, that is the key
point. Thus he has no idea what safe symbol names to use.
What if "updateGui()" does "rm -rf /" ?
What if "updateGui()" always does a null pointer dereference?
You will have a bugged/malicious function in your code base, one
very easy to detect and fix. Nothing in common with discussed
problem.
