That is because in Perl '$' indicates the variable stores a scalar value
and is not the interpolation indicator.  In Perl the '$' is a part of
the variable name. They look the same, but semantically they are quite
different. Of course, Larry Wall, (the inventor of Perl) was well versed
in shell scripting and he created a language which would look familiar
to shell scripters who use sed, awk, etc in their scripts.
