Gimmicks and hacks to make some of my other modules more robust and less demanding of others.

Latest release 20250428: Define Buffer from collections.abc.Buffer, or from typing.ByteString for older Pythons.

Short summary:

• open_append: Ghastly hack to open something for append entirely because some Linux systems do not let you open a character device for append. Tries sane 'a' and falls back through 'r+' and finally to 'w' only if path refers to a character device.

Module contents:

• debug(*a, **kw): Wrapper for debug() which does a deferred import.
• error(*a, **kw): Wrapper for error() which does a deferred import.
• exception(*a, **kw): Wrapper for exception() which does a deferred import.
• info(*a, **kw): Wrapper for info() which does a deferred import.
• log(*a, **kw): Wrapper for log() which does a deferred import.
• open_append(path): Ghastly hack to open something for append entirely because some Linux systems do not let you open a character device for append. Tries sane 'a' and falls back through 'r+' and finally to 'w' only if path refers to a character device.
• r(obj): simplistic versions of cs.lex r() and s()
• trace(*a, **kw): Wrapper for info() which does a deferred import.
• warning(*a, **kw): Wrapper for warning() which does a deferred import.
