Hi,
my question is probably naive, please bear with me.
Every time I look inside .pir files the same question comes to my mind
Why a simple syntax sugar is not invented to introduce a couple of macro-like
straightforward expansions
if COND {
}
transform to
unless COND goto AUTOGEN_LABEL_XXX
.....
AUTOGEN_LABEL_XXX:
likewise
unless COND {
}
and
if COND {
} else {
}
This way following function inside ./languages/perl6/src/classes/Bool.pir:
.sub 'perl' :method
if self goto false
.return ('Bool::False')
false:
.return ('Bool::True')
.end
could be written as
.sub 'perl' :method
if self {
.return ('Bool::True')
}
else {
.return ('Bool::False')
}
.end
which will be expanded as
.sub 'perl' :method
unless self goto autogenerated-label-1
.return ('Bool::True')
goto autogenerated-label-2;
autogenerated-label-1:
.return ('Bool::False')
goto autogenerated-label-2:
.end
these straightforward expansions will free PIR-programmers from inventing
labels every time, and introduces better readability.
Best regards,
Vadim.
