# GCC WARNING
comparison between signed and unsigned integer expressions
# EXPLANATION
Perl `scalar` operation compiles to C++ `size()` function w/ return type unsigned_integer
index variable `i` must also be unsigned_integer to avoid warning
# PERL INPUT, INCORRECT
for my integer $i ( 0 .. ( ( scalar @{ $self->{bodies} } ) - 1 ) ) { ... }
# C++ OUTPUT, INCORRECT
integer i;
for ( i = 0; i < (this->bodies.size()); i++ ) { ... }
# PERL INPUT, CORRECT
for my unsigned_integer $i ( 0 .. ( ( scalar @{ $self->{bodies} } ) - 1 ) ) { ... }
# C++ OUTPUT, CORRECT
unsigned_integer i;
for ( i = 0; i < (this->bodies.size()); i++ ) { ... }
