TITLE

P6C::IMCC::prefix - Prefix operators (i.e. functions and control structures)

FUNCTIONS

prefix_if

if/elsif/elsunless/else sequence

prefix_while

while() expression

gen_sub_call

Do a subroutine call.

Arguments: $x : a P6C::prefix representing the function call %options : the only valid option currently is 'is_rule'

XXX: currently ignores context. We don't have a way of communicating context to functions anyways, so this isn't a problem.

FIXME: this also heavily uses the P6C::IMCC::Sub object pulled out of %P6C::IMCC::funcs. Which would be good to eliminate wherever possible.

find_named_param

Look up a named parameter by name in a signature, and return the P6C::sigparam object if found. This only looks at named parameters, not positional params.

find_positional_param_by_name

Look up a positional parameter by name in a signature, and return the P6C::sigparam object if found. This only looks at positional parameters, not named parameters. (Remember, positional params also have names.)

categorize_args

Split up an array of args into positional params, named params whose names are statically known, named parameters whose names are unknown at compile time, etc.

prefix_for

for() statement

prefix_neg

unary minus

prefix_pos

unary plus

prefix_bitxor

unary bitwise negation

val_noarg

XXX: pretend that the block has a no-argument prototype, since otherwise it will complain. This is the wrong behavior for the topicalizing control structures, but we don't support them yet, anyways.

val_topical

???

prefix_foreach

foreach() statement

wrap_with_catch

I assume this does something like what it says it does.

prefix_try

Run something in a try { } block. Implementation just calls wrap_with_catch() with no catch block.

prefix_return

Return a value.

prefix_when

Handle a case in a given/when clause.

prefix_default

Default case in a given{} block.

prefix_given

The all-magical given/when construct.

prefix_defined

Test whether something is defined.
