Was originally written as a way to fix a failing property test on the
program_builder; but the program builder is now gone. This function
is still useful to have around.
Params being unused were being incorrectly reported.
This was because params need to be initialized
at a scope above both the validator functions. This
manifested when using a multi-validator where one of
the params was not used in both validators.
The easy fix was to add a field called
`is_validator_param` to `ArgName`. Then
when infering a function we don't initialize args
that are validator params. We now handle this
in a scope that is created before in the match branch for
validator in the `infer_definition` function. In there
we call `.in_new_scope` and initialize params for usage
detection.
Fixes#472.
This also partially addresses #195. However, as pointed out in one of
the comment, there's no 'official rule' when it comes to what should
be considered valid escape sequences. Haskell relies mostly on the
AttoParsec library and Rust also has its own set of rules.
This is in particular true for unicode escape sequences, but there is
a common middleground for some usual single character escapes such as
\n or \\. So we now at least support these.
For more complicated escape sequence, please refer to #195 for now and
keep the discussion going there.
One involving zero args being hoisted instead of compiled and replaced.
Second involving not updating a function's dependeny function scope. Which then hoisted to a lower scope and caused free unique
* new module scope which holds some ancestor logic
