What I meant more was having trigger words that designate what’s happening.
So something like transform dataset1 dataset2 could easily be transform source dataset1 destination dataset2 while still keeping everything else the same. Granted it’s still different from having the comma separated things, but since the intention appears to be that both toolboxes will be merged at some point, while using the singular toolbox you will have to jump around between syntax/styles while doing a single task (since generally speaking, doing data stuff will also be coupled with doing decomposition stuff, so in a larger/contextual patch, there won’t be as clear a hierarchical separation between the TB1 processes and TB2 ones.
