runCatching catches Throwable? about kotlin-result

[michaelbull]

Because that's what Kotlin's own Result type (which came after this library and is far more limited than this library) does.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/run-catching.html#runcatching

Calls the specified function block and returns its encapsulated result if invocation was successful, catching any Throwable exception that was thrown from the block function execution and encapsulating it as a failure.

When this library was initially written I had an analogous method named Result.of which used Exception instead of Throwable, but then I deprecated it in favour of a top-level runCatching function to be consistent with how the stdlib operates.
