semgrep 0.106.0 on Python PyPI

0.106.0 - 2022-07-21

metavariable-comparison: The metavariable field is now optional, except
if strip: true. When strip: false (the default) the metavaraible field
has no use so it was pointless to require it. (metavariable-comparison-metavariable)
metavariable-comparison now also works on metavariables that cannot be evaluated
to simple literals. In such cases, we take the string representation of the code
bound by the metavariable. The way to access this string representation is via
str($MVAR). For example:
```
- metavariable-comparison:
    metavariable: $X
    comparison: str($X) == str($Y)
```
Here $X and $Y may bind to two different code variables, and we check whether
these two code variables have the same name (e.g. two different variables but both
named x). (pa-1659)
When running an SCA scan with semgrep ci --sca,
SCA findings will no longer be considered blocking if they are unreachable. (sca-128)

Fixed a regression in name resolution that occurred with metavariable patterns (gh-5690)
Rust: Fixed a bug with matching for scoped identifiers
Basically, scoped identifiers were only looking at the last identifier. So something like A::B::C would result in something like C. (gh-5717)
