Text::KnuthPlass fails to build for me (Windows 10, Strawberry Perl 5.26.1). It's failing (several type mismatches?) in the XS compile stage:
Configuring S/SI/SIMON/Text-KnuthPlass-1.02.tar.gz with Build.PL
Created MYMETA.yml and MYMETA.json
Creating new 'Build' script for 'Text-KnuthPlass' version '1.02'
