Stream insertion operators

== Synopses

Declared in `<balst_stacktrace.h>`

Write the value of the specified `object` to the specified output `stream` in a single‐line format, and return a reference to `stream`. If `stream` is not valid on entry, this operation has no effect. Note that this human‐readable format is not fully specified and can change without notice. Also note that this method has the same behavior as `object.print(stream, 0, ‐1)`, but with the attribute names elided.
