Out of curiosity, might there be any convenient way to support
heredoc parameters in PIR function calls? (I suspect the answer
is "no", but thought I'd ask just in case.)
Currently PGE builds code to be compiled by emitting a sequence
of function calls, each call appends another line of output to a
string pmc. Of course, each of these calls takes some amount of
overhead, and it might be nice if instead of writing
emit(code, " lastpos = length target")
emit(code, " gpad = new PerlArray")
emit(code, " rcache = new PerlHash")
emit(code, " captscope = mob")
emit(code, " bsr %s", label)
one could instead write:
emit(code, <<"CODE", label)
lastpos = length target
gpad = new PerlArray
rcache = new PerlHash
captscope = mob
bsr %s
CODE
thus converting the five emit statements into one. Yes, I know I can do
$S0 = <<"CODE"
...
CODE
emit(code, $S0, label)
but I'm not a fan of writing the $S0 variables -- they seem to distract
the code. I may just go with something like
code .= " lastpos = length target"
code .= " gpad = new PerlArray"
code .= " rcache = new PerlHash"
code .= " captscope = mob"
emit(code, " bsr %s", label)
which at least changes the first four to be parrot ops instead
of function calls for each.
Any other thoughts or suggestions?
