+** TODO Issues when using ~-L|--load-path~ along with ~guix time-machine~
+
+I have found that source changes are not detected when using ~guix time-machine -C
+channels.scm -- <CMD>~ when ~<CMD>~ uses the ~-L|--load-path~ option. However, ~guix <CMD>~
+on its own does detect source changes.
+
+It's worth noting that I've missed this before because *I think* that when using ~guix
+time-machine~ with ~-L~ the source is still parsed/evaluated, so syntax errors are detected.
+
+This needs to be further investigated and is likely a guix bug.
+
+Another note: It appears that if ~-L~ is provided on both sides of the guix time-machine
+command, it works as expected and detects source changes. This does not appear to be
+consistent though, and sometimes using ~-L~ only on the rhs works as expected.
