Aw shucks, discovered an issue
db.withTransaction:
t["fuz"] = "buz"
if false:
t.commit
# does not add anything
# transaction not ended, program blocks
Run
Statically ensuring a tagged proc is called in all code paths seems more
trouble than it's worth.
@Araq's approach really is simple to implement (like old Unix tools 😉) Maybe
with different naming? "hopefully obvious" might work as well as "hopefully
familiar"...
# (a)
db.readonly:
t["fuz"] = "buz"
# always adds reset
db.writable:
t["fuz"] = "buz"
# always adds commit
Run
Or perhaps supershort, familiar and autochoose (no manual `commit`/`reset`)
# (b)
with db:
t["foo"] = bar
Run
Or the same by default with more control
# (c)
type Mode = enum[auto, readonly, writable]
with db:
t["foo"] = bar
# commits
with db readonly:
t["foo"] = bar
# resets
Run
The agony.
