It seems tautology and say nothing. What is "convenience of an expression"? Is it needed to make Python more readable language? Anyway, If "there is expression" is the main reason for this proposal, symbolic operator is not necessary. `new = d1.updated(d2)` or `new = dict.merge(d1, d2)` are enough. Python preferred name over symbol in general. Symbols are readable and understandable only when it has good math metaphor. Sets has symbol operator because it is well known in set in math, not because set is frequently used. In case of dict, there is no simple metaphor in math. It just cryptic and hard to Google. -- INADA Naoki <songofaca...@gmail.com> _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
