That's a strong deduction to make from a casual remark!  But since BCPL
has clearly made other changes not listed there, I don't think you can
conclude that removing types is literally the *only* change.

Thanks.  I'm be interested to hear what he says (and I wonder why I
never thought to ask myself).  It seems unlikely that break was invented
for BCPL, but you never know...  CPL seems to have had a rather chaotic
design, so it may have had many features come and go.  And what
influences there were around at the time is hard to determine now.
