But in the case of a bareword, it assumes you mean a module. .PP This gives nasty overhead when you are trying to dynamically require modules at runtime, since you will need to change the module notation (\f(CW\*(C`Acme::Comment\*(C'\fR) to a file notation fitting the particular platform you are on. .PP \&\f(CW\*(C`load\*(C'\fR eliminates the need for this overhead and will just \s-1DWYM\s0. .SH "Rules" .IX Header "Rules" \&\f(CW\*(C`load\*(C'\fR has the following rules to decide what it thinks you want: .IP "\(bu" 4 If the argument has any characters in it other than those matching \&\f(CW\*(C`\ew\*(C'\fR, \f(CW\*(C`:\*(C'\fR or \f(CW\*(C`\*(Aq\*(C'\fR, it must be a file .IP "\(bu" 4 If the argument matches only \f(CW\*(C`[\ew:\*(Aq]\*(C'\fR, it must be a module .IP "\(bu" 4 If the argument matches only \f(CW\*(C`\ew\*(C'\fR, it could either be a module or a file. We will try to find \f(CW\*(C`file\*(C'\fR first in \f(CW@INC\fR and if that fails, we will try to find \f(CW\*(C`file.pm\*(C'\fR in \f(CW@INC\fR. If both fail, we die with the respective error messages. .SH "Caveats" .IX Header "Caveats" Because of a bug in perl (#19213), at least in version 5.6.1, we have to hardcode the path separator for a require on Win32 to be \f(CW\*(C`/\*(C'\fR, like on Unix rather than the Win32 \f(CW\*(C`\e\*(C'\fR. Otherwise perl will not read its own \f(CW%INC\fR accurately double load files if they are required again, or in the worst case, core dump. .PP \&\f(CW\*(C`Module::Load\*(C'\fR cannot do implicit imports, only explicit imports. (in other words, you always have to specify explicitly what you wish to import from a module, even if the functions are in that modules' \&\f(CW@EXPORT\fR) .SH "ACKNOWLEDGEMENTS" .IX Header "ACKNOWLEDGEMENTS" Thanks to Jonas B.
