+## Import Module
+
+There's no need to import a library before it's needed. But many libraries can 
+be imported for the first time from many places. It would be nice to have a 
+standardized way to check if a module has been imported.
+
+Some thoughts:
+
+* On import, add the module's name to a global variable
+* On check, see if module's name is in global variable
+* On teardown, unset the global variable
+
+Or, I could just check `declare -F` for the function I want.
+
+Or, I could source without a check. A function-only library should be idempotent.
+
+## Improve Logs with Stderr Capture
+
+You can capture stderr, stdout like this:
+
+``` bash
+echo "test output" > .test \
+  && { TEST="$(<.test)"; echo "$TEST"; rm .test; }
+do_whatever "$TEST"
+unset TEST
+``symlink`
