My recent post
in substance my faith on Perl6 macros as a device to
cast in syntax common programmatic patterns which were not integrated
in Perl6 standard syntax. It makes sense because a programmatic pattern may be common in some context but
not worthwhile to capture in the standard language.
It can also be a way to experiment syntactical devices that
can eventually find their way in Perl6 standard syntax.
I was pointed to
this artima weblog by a (not yet archived) post in ll1. It says that macro
is one of the devices that distinguish LFSPs (Languages For Smart
People) and LFMs (Languages for the masse) and goes to
analyse their implications.
The blog author cites Gilad Bracha who advocates against the introduction
of macros in Java because it is a LFM:
The advantages of Java is that it easily serves as a lingua franca - everyone can read a Java program and understand what is going on. User defined macros destroy that property.
What do you think?
