Are raw commands available in StackExchange.Redis?

Is there any functionality in StackExchange.Redis that allows you to execute raw commands directly? Like I'd provide a string with the command, e.g. (hypothetical code below):

conn.Send("ZADD mysortedset 1 john");

I know there are methods available for just about every command including ZADD, but that's not the point.

The introduction of "modules" made this a lot more relevant; this API now exists in Execute(...). See: http://blog.marcgravell.com/2017/04/stackexchangeredis-and-redis-40-modules.html

Previously:

Not currently, and I'd be dubious of the benefit. In particular, doing this wouldn't allow correct routing on sharded instances (twemproxy, redis-cluster, etc), wouldn't allow renamed command-map usage, and wouldn't allow binary keys / values to be used. It would also allow very risky and concept-breaking commands to be used inappropriately, such as select, watch/multi/exec, blocking-pops brpop/blpop/brpoplpush - all of which would be catastrophic to the multiplexer (well, select isn't a biggie, as it can just be configured such that Send leaves the db undefined - the code for that already exists thanks to some similar examples). It would also expose dangerous commands that should never need to be used from a general library: debug segfault, client pause, etc - again, all very bad ideas.

But sure, in theory it could be done... but I would really want to see a compelling reason to offset the many problems above.

At the moment, the most exposed way to execute ad-hoc commands is via ScriptEvaluate - it would involve writing Lua, of course.
