# uncommonlisp — Python + C + Assembly implementations
# ═══════════════════════════════════════════════════════════════════
#
# Implementations:
#   Python    uncommonlisp.py         bytecode VM, full continuations, portal
#   C         c/uncommonlisp          tree-walker + bytecode VM + x86_64 JIT
#   Assembly  asm/uncommonlisp        pure x86_64, no libc, 13KB binary
#
# Test suites:
#   make test           Python unit/integration (571 tests)
#   make c-test         C unit/integration + JIT (76 tests) + functional (114)
#   make asm-test       Assembly unit/integration/functional (75 tests)
#   make functional-test  Shared .lsp suite in Python + C (114 each)
#   make test-all       Everything (836 total)
#
# Other:
#   make bench-all      Benchmarks for Python + C
#   make friction       Head-to-head timing: Python vs C vs CPython
#   make examples       Run examples in Python + C, compare output
#   make docs           Generate architecture diagrams
#   make whitepaper     Build PDF whitepaper
#   make clean-all      Clean everything
