back to pattern-driven dispatch (now working, thanks to @tvdstorm)
separate replace, (un)fold, extract/inline, renameN, equate, splitN
separate factor, rassoc, lassoc, iterate
separate distribute, massage, narrow, widen
separate renameL, unlabel, designate; enforcing Rascalware
coevolve with Rascal & Rascalware (not yet complete)
separate renameS, renameT, concretize, abstractize, splitT, concatT
separate appear, disappear, inject, permute, project
separate yaccify, deyaccify, anonymize, deanonymize
separate chain, unchain, reroot, abridge, detour
separate unite, vertical, horizontal, addH, removeH
separate addV, removeV, define, undefine, redefine, eliminate, introduce, import
separate upgrade and downgrade; final cleanup
Merge branch 'modular-xbgf'
somewhat unstable state: going back to one problem only
