New variable type: "regexp", --> Node_hardregexp. (Need a better name).
Syntax: @/.../
Use:
a = @/.../ # a now has type regexp
a = foo(1, "bar", @/.../) # pass a regex to user defined function
New function:
t = typeof(exp) # "array", "regexp", "scalar"
# Open: "scalar" vs. "scalar_s" / "scalar_n"
Obsolete function:
isarray(exp)
Conversions:
r = @/.../
s = r "" # what happens? becomes regex string?
s = r + 0 # what happens? treat as numeric 0?
Why?
Allows passing regexes through user defined functions
Allows passing regexes through indirect funtion calls
In general, this is a gap in the language
