And if the sentence begins with "e.."? :)

Good catch! The order must be reversed to reflect the greed. `DB<8> x 'eeeA1234eB' =~ /(e+\|e{0})(.)/ 0 'eee' 1 'A' DB<9> x 'A1234eB' =~ /(e+\|e{0})(.)/ 0 '' 1 'A' DB<10> x 'A1234eB' =~ /(e+)(.)/ 0 'e' 1 'B' DB<11>` [download] Thanks!

The order must be reversed to reflect the greed.

  DB<8> x 'eeeA1234eB' =~ /(e+|e{0})(.)/
0  'eee'
1  'A'
  DB<9> x 'A1234eB' =~ /(e+|e{0})(.)/
0  ''
1  'A'
  DB<10> x 'A1234eB' =~ /(e+)(.)/
0  'e'
1  'B'
  DB<11>
