A PHP internals discussion about adding a static factory method (`createFrom`) to `BcMath\Number` to enable callable-style initialization. The proposal is motivated by the desire to use the class with first-class callables (FCCs) and partial function application (PFA) syntax. Supporters like Larry Garfield and Marco Pivetta favor static factory methods as an established pattern, though Pivetta suggests a more descriptive name like `::fromValueAndScale()`. Opponents, including Gina P. Banyard and Tim Düsterhus, argue the better solution is to make FCCs/PFAs work directly on constructors and `new` expressions, avoiding the need to add static factories to every class. Banyard mentions an active PR to clean up constructor semantics that could enable this.
