This PR adds a detailed report of the transpilation analysis performed on five Python test files from the py2v_transpiler/tests/input/transpile/ directory.

The analysis highlights several recurring issues in the generated V code, including:

  • Incompatibility of Python string method names (strip, lower, upper, find) with V's standard library.
  • Lack of explicit variable captures in V closures/lambdas.
  • Incorrect translation of Python's string reversal slicing ([::-1]).
  • Type errors in variadic parameter (*args) translation.
  • Non-idiomatic and invalid V syntax for filter and map operations.

The findings are documented in transpilation_issues.md.
