Assertions, Compiler Support, Operators, & Documentation

New in this release

• Idiomatic assertions: Julienne's expressive idioms can now be used in assertions that are conditionally compiled and executed inside a user's procedures. See the Assertions and Writing Assertions sections in this repository's root-directory README.md file.
• Expanded compiler support: Run the Julienne test suite to see the tests, if any, that are skipped (unsupported) with your compiler.
  • GCC 15: full support -- the only unsupported feature (vector_test_description_t) is superseded by the newer .all. operator, is therefore deprecated and likely will be removed at some point).
  • GCC 13-14:- the only unsupported feature, bracket(), stems from a compiler bug that has been fixed in GCC 15.
• New defined operations:
  • Relative tolerances: the two newly supported expressions below are equivalent.
    • x .approximates. y .withinFraction. 0.01
    • x .approximates. y .withinPercentage. 1.0
• Expanded documentation: The root-directory README.md file has been updated to
  • Describe the above changes,
  • Provide background on the philosophy behind Julienne,
  • Give more detail on the functional programming patterns that Julienne supports,
  • Update the known issues with GCC,
  • Tabulate example expressions in a way that comprehensively covers Julienne operators and operand types, and
  • Tabulate the string_t constructor functions in a way that
    • Partially demonstrates the numeric types that Julienne can convert to strings,
    • Comprehensively demonstrates string_t's defined operations: .csv., .sv., .cat., and //., and
    • Partially demonstrates the string_t functionality that Julienne provides.

Issue #70 provides a To Do list that includes items to add to the README.md to make it closer to a comprehensive delineation of Julienne's capabilities.
