in reply to print output from the text file.

http://blogs.perl.org/users/jeffrey_kegler/2013/01/making-dsls-even-simpler.html

$ perl marpa-scannerless-calculator.pl --stdin W=1; ( ( 0.3802 + ( 13.4739 * ( ( W / 0.9 )^(1/2) ) ) ) + ( 4.6272 * ( + W / 0.9 ) ) ) ^Z result = 19.7242709884476 value of "W" = "1"

Wouldn't you know it, perl agrees

$ perl -E " $W=1; say ( ( 0.3802 + ( 13.4739 * sqrt( ( $W / 0.9 ) ) ) +) + ( 4.6272 * ( $W / 0.9 ) ) ); " 19.7242709884476

Being able to specify a qr{} would simplify this DSL immensely

Make of it what you will
