    On my system, ∞ is inf, so I needed to lowercase the I.

    Here's my shorter version:

    # 1 2 3 # 12345678901234567890123456789012345 perl -E 'say$_=3;/i/?die:say$_*=$_ while--$_' # old perl -E 'say$_=3;say$_*=--$_ while$_&&!/i/' # new
    ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

      Playing with your proposal a bit leads to

      $_=3;say,$_*=--$_ while!/i/

        Your proposition lacks the final infinite though. But in any case you can win one char with until. say$_=3;say$_*=--$_ until/i/
