是什么启发了Ruby的=开始.. =结束注释块语法？

Question

I know that a lot of Ruby was inspired by Perl (eg STDIN as a global constant) or Unix shell (eg the <<END heredoc syntax). But I don't know where the block comment syntax comes from. The syntax:

=begin
This is a comment line
it explains that the next line of code displays 
a welcome message
=end

Where does this come from? My knowledge of Perl is sketchy. Is it Perl?

Answer 1

yes, this is Perl

Perl uses

=begin
This is a comment line
it explains that the next line of code displays 
a welcome message
=cut
