# Function call overhead test

# local variable. This is commonly known optimization for overly dynamic
# languages (the idea is to cut on symbolic look up overhead, as local
# variables are accessed by offset, not by name)

bench: Add test for function call overhead. For a trivial operation, calling a function is 5 times slower than doing operation inline. 2014-06-18 20:20:34 -04:00			`# Function call overhead test`

tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting. 2020-03-22 22:26:08 -04:00
