As discussed at https://matrix.to/#/!fLeHeojWgBGJlLNdLC:matrix.org/$DHCPeZQ1aty_1l_nNHo_5F8Uwb3t29N1zuabWa5qLzM?via=matrix.org&via=element.io&via=vector.modular.im
Peg is used in the literal sense:
> a short pin or bolt, typically tapered at one end, that is used for securing something in place, hanging things on, or marking a position.
Looking for an `MatrixClient`? Just look for the `MatrixClientPeg` on the peg board. So you'll find a `MatrixClient` hanging on the `MatrixClientPeg`.
Maybe you're more familiar with these alternative names like `MatrixClientSingleton` but that's a bit long and Java-y or `MatrixClientHandle` in the win32 world.
