These kinds of issues are excellent commercials for why the strictness of a language like F# (or OCaml, Haskell, etc), is such a powerful tool for correctness:

1) Outside of initialization, assignment is done with the `<-` operator, so you're only potentially confused in the opposite direction (assignments incorrectly being boolean comparisons).

2) Return types and inputs are strictly validated so an accidental assignment (returning a `void`/`unit` type), would not compile as the function expects a bool.

3) Immutable by default, so even if #1 and #2 were somehow compromised the compiler would still halt and complain that you were trying to write to something unwriteable

Any of the above would terminally prevent compilation, much less hitting a code review or getting into production... Correctness from the ground up prevents whole categories of bugs at the cost of enforcing coding discipline :)

This is why I love F# but if you jump between f# and c# your muscle memory will suffer.
